Products

• EEU/20KN: Universal Material Testing Unit — EDIBON: EEU/20KN is a bench universal testing machine for tensile, compression and bending tests on small specimens. Load and extension are recorded during the test so the stress strain curve, yield point, tensile strength and elongation can be obtained.
• EEDB: Brinell Hardness Testing Unit — EDIBON: EEDB is a bench hardness tester that uses the Brinell method. A hardened ball indenter is pressed into the specimen under a known load and the diameter of the impression is measured optically to give the Brinell hardness number.
• EBVR: Brinell, Vickers & Rockwell Hardness Testing Unit — EDIBON: EBVR is a bench hardness tester covering the Brinell, Vickers and Rockwell methods on one machine. Indenters and loads are changed for each scale so students can compare hardness values obtained by different methods on the same material.
• EEFCR: Creep Testing Unit — EDIBON: EEFCR is used to study creep in metals and polymers at room and elevated temperature. A constant load is applied to a specimen and extension is recorded over time, giving the primary, secondary and tertiary stages of the creep curve.
• EEF: Fatigue Testing Unit — EDIBON: EEF is a rotating bending fatigue machine. A specimen is loaded as a cantilever and rotated so its surface sees alternating stress, and cycles to failure are counted to build up an S-N curve. A computer controlled version, EEFC, is also published.
• EEICI: Charpy and Izod Impact Test Unit — EDIBON: EEICI is a pendulum impact tester for Charpy and Izod tests. The pendulum is released from a set height to break a notched specimen and the absorbed energy is read on a scale, so notch shape and temperature effects can be studied. A 300 J version, EEICI/300, is also published.
• MTP: Torsion and Bend Unit — EDIBON: MTP allows torsion and bending tests on the same frame. Specimens are twisted or bent by a screw mechanism while torque, angle of twist, load and deflection are measured, giving the modulus of rigidity and the modulus of elasticity.
• MTB: Torsion Unit — EDIBON: MTB is used for torsion tests on metal bars. Torque is applied through a worm gear and measured with a load cell while the angle of twist is read, so the modulus of rigidity and behaviour past the elastic limit can be studied.
• MTT: Torsion Test Unit (30Nm) — EDIBON: MTT is a bench torsion machine for specimens loaded up to 30 Nm of applied torque. Torque and angle of twist are recorded through the test so students can obtain the shear stress and shear strain curve and the modulus of rigidity.
• MTTU: Tensile Tester Unit — EDIBON: MTTU is a bench tensile tester for small metal and plastic specimens. Load and extension are measured as the specimen is pulled to failure, giving the stress strain curve, the yield and tensile strength and the percentage elongation.
• TIAC: Computer Controlled Acoustic Impedance/Acoustic Insulation Study Unit — EDIBON: TIAC is a computer controlled impedance tube for acoustic testing of materials. The sound absorption coefficient and acoustic impedance of samples are measured over a frequency range and recorded through the data acquisition system.
• TDRC: Computer Controlled Noise Control Demonstration Unit — EDIBON: TDRC is a computer controlled unit for studying noise control. Sound levels are measured with and without barriers, enclosures and absorbing linings, so the insertion loss of each treatment can be quantified across the frequency range.
• TCMC: Computer Controlled Thermal Conductivity of Building and Insulating Materials Unit — EDIBON: TCMC is a computer controlled unit for measuring the thermal conductivity of building and insulating materials. A sample is held between heated and cooled plates and the steady state heat flow and temperature difference are recorded.
• MCAM: Practical Casting Kit: Modeling and Sand Casting of Solid Parts — EDIBON: As an essential educational tool for teaching the fundamentals of casting, EDIBON developed the Practical Casting Kit: Modeling and Sand Casting of Solid Parts, "MCAM".
• MCEN: Practical Casting Kit: Centrifugal Casting — EDIBON: As an essential educational unit for teaching the fundamentals of centrifugal casting, the Practical Casting Kit: Centrifugal Casting, "MCEN", was designed by EDIBON. It enables students to build practical skills in centrifugal casting techniques, allowing for a detailed and thorough understanding of the processes involved.
• MCLA: Practical Casting Kit: Modeling and Sand Casting of Hollow Parts — EDIBON: Developed by EDIBON as an essential educational tool for teaching the fundamentals of casting, this is the Practical Casting Kit: Modeling and Sand Casting of Hollow Parts, "MCLA".
• EEFC: Computer Controlled Fatigue Testing Unit — EDIBON: Designed by EDIBON, the Computer Controlled Fatigue Testing Unit, "EEFC", allows the fatigue strength of materials to be studied. To that end, fatigue tests are carried out using different materials and notches.
• EEICI/300: 300 Nm Charpy and Izod Impact Testing Unit — EDIBON: Toughness in impact tests of stainless steel, copper (Cu), brass (Cu+Zn alloy), and aluminum specimens can be studied with the 300 Nm Charpy and Izod Impact Testing Unit, "EEICI/300", designed by EDIBON.
• EFOC: Computer Controlled Photoelasticity Unit — EDIBON: Designed by EDIBON for photoelasticity practices, the Computer Controlled Photoelasticity Unit, "EFOC", illustrates the subjects of photoelasticity theory, elasticity theory, strength of materials, and structure theory.
• EFOV: Computer Controlled Photoelasticity Unit with Artificial Vision System — EDIBON: For photoelasticity practices illustrating the subjects of photoelasticity theory, elasticity theory, strength of materials, and structure theory, EDIBON designed the Computer Controlled Photoelasticity Unit with Artificial Vision System, "EFOV".
• PP 40: Pellet Press — Retsch: Benchtop hydraulic press that compacts powdered samples into solid pellets for X-ray fluorescence analysis. Pressing force is up to 40 tons. Consistent pellet density matters for XRF because a poorly formed pellet changes the measured intensity, so a controlled press is part of the analytical chain rather than an accessory.
• TG 200: Fluid Bed Dryer — Retsch: Fluid bed dryer that dries bulk material in a stream of warm air before milling or sieving, so moisture does not distort the particle size result. The material is held in suspension by the air stream, which gives short drying times and even treatment without local overheating.
• DR 100: Vibratory Feeder — Retsch: Vibratory feeder that meters pourable bulk material and fine powder into a mill, divider or analyser at a steady rate. A continuous, even feed is what makes throughput and grinding results reproducible, particularly when a mill is running unattended.
• UR Series: Ultrasonic Baths — Retsch: Ultrasonic baths for cleaning test sieves and grinding tools between samples. Removing residue from a sieve mesh matters because trapped particles change the effective aperture, and ultrasonic cleaning reaches the mesh without the mechanical damage that brushing causes.
• BB 50: Jaw Crusher — Retsch: The compact benchtop jaw crusher in the range, designed for laboratories where bench space is limited and sample quantities are small. It crushes medium hard, hard, brittle and tough material down to below 0.5 mm, with the gap width set digitally in 0.1 mm increments so a size reduction step can be reproduced exactly.
• BB 200: Jaw Crusher — Retsch: Floor standing jaw crusher aimed at fineness rather than feed size, taking medium hard, hard, brittle and tough material down to below 2 mm at up to 300 kg per hour. Grinding tools are available in several materials, so the crusher can be matched to samples where contamination from the jaws would affect the later analysis.
• BB 250: Jaw Crusher — Retsch: Jaw crusher built around ergonomic handling, with the crushing chamber and collection vessel positioned for easy access during repeated sample changes. It handles large feed pieces of medium hard, hard, brittle and tough material and reduces them to below 2 mm at up to 300 kg per hour.
• BB 300: Jaw Crusher — Retsch: Jaw crusher aimed at large feed size, accepting bigger pieces than the BB 200 and reducing them to below 5 mm at up to 600 kg per hour. The wider gap setting range suits primary crushing of rock, ore and construction material before a secondary mill takes the sample to analytical fineness.
• BB 400 XL: Jaw Crusher — Retsch: Jaw crusher combining a large feed opening with ergonomic handling, reducing medium hard, hard, brittle and tough material to below 2 mm at up to 400 kg per hour. The XL designation refers to the enlarged crushing chamber relative to the standard models.
• BB 500 XL: Jaw Crusher — Retsch: Jaw crusher with a steep crushing chamber and powerful drive, giving crushing kinematics that take 90 per cent of the product below 0.5 mm in a single pass. Throughput reaches 500 kg per hour, which suits mineral processing and cement laboratories handling continuous sample streams.
• BB 600 XL: Jaw Crusher — Retsch: The largest jaw crusher in the Retsch range, taking the biggest feed pieces and delivering the highest throughput at 3500 kg per hour. Gap width is set with spacer plates from 6 mm to 60 mm. It is used where sample volumes are at pilot plant rather than laboratory scale.
• ZM 300: Ultra Centrifugal Mill — Retsch: Rotor mill that grinds soft, medium hard, brittle and fibrous material to below 40 µm by impact and shearing between a rotor and a fixed ring sieve. Speed is freely selectable up to 23,000 rpm and the ring sieve sets the final fineness, so one mill covers a wide fineness range. Temperature monitoring protects heat sensitive samples.
• SR 300: Rotor Beater Mill — Retsch: Rotor beater mill for coarse and fine size reduction of soft to medium hard material, working by impact against a fixed beater arrangement. Speed is adjustable in 500 rpm steps so grinding can be tuned to the sample, and a ring sieve defines the final fineness down to below 50 µm.
• SK 300: Cross Beater Mill — Retsch: Cross beater mill for coarse and fine size reduction of medium hard and brittle material such as coal, coke, minerals and slag. It runs from laboratory to pilot plant scale and the adjustable rotor speed with an exchangeable bottom sieve sets the final fineness down to below 100 µm.
• HM 200: Hammer Mill — Retsch: Hammer mill for crushing and pulverising large sample volumes of medium hard, hard, brittle, tough and fibrous material at up to 1500 kg per hour. Feed material is reduced by impact from swinging hammers and passes a bottom sieve at below 0.8 mm. Its size and throughput place it between laboratory and pilot plant duty.
• SM 50: Cutting Mill — Retsch: Benchtop cutting mill for small quantities of soft, medium hard, tough, elastic and fibrous material such as plastics, textiles and plant matter. The grinding chamber design allows a high proportion of the sample to be recovered, which matters when only a small amount of material is available.
• SM 100: Cutting Mill — Retsch: Basic model cutting mill for routine size reduction of soft, medium hard, elastic and fibrous material. A fixed 1,500 rpm rotor cuts the sample against stationary knives until it passes the bottom sieve, which sets the final fineness between 0.25 mm and 20 mm.
• SM 200: Cutting Mill — Retsch: Standard cutting mill for preliminary size reduction of a wide range of soft, medium hard, tough, elastic and fibrous materials. It has a stronger drive than the SM 100 and a chamber arranged for straightforward cleaning between samples, which is the usual bottleneck when running mixed material types.
• SM 300: Cutting Mill — Retsch: High performance cutting mill with RES technology, in which a flywheel stores energy and releases it into the cut, so the rotor holds speed through tough material that would stall a conventional mill. Speed is adjustable from 100 to 3000 rpm, which lets heat sensitive samples be run slowly.
• RM 200: Mortar Grinder — Retsch: Motorised mortar and pestle that grinds, mixes and triturates soft, hard, brittle and pasty material, wet or dry, to below 10 µm. It reproduces the manual mortar process with a set pestle pressure and a fixed 100 rpm speed, so the result does not depend on who is operating it.
• DM 200: Disc Mill — Retsch: Disc mill that reduces medium hard, hard and brittle material between a fixed and a rotating grinding disc, with the gap set continuously from 0.05 mm to 5 mm. It covers both preliminary and fine grinding, and the choice of disc material governs how fine it will go and how much contamination is introduced.
• RS 200: Vibratory Disc Mill — Retsch: Vibratory disc mill that homogenises medium hard, hard, brittle and fibrous samples to below 20 µm in seconds, which is the fineness spectral analysis needs. A grinding set of rings and a puck oscillates horizontally inside a sealed jar, so the sample is not exposed and loss of fines is limited.
• RS 300 XL: Vibratory Disc Mill — Retsch: Large capacity vibratory disc mill taking batches from 35 ml up to 2,000 ml, for laboratories preparing large samples for spectral analysis. It reaches the same sub 20 µm fineness as the RS 200 but with grinding sets up to 2 litres, so a bulk sample does not have to be split before grinding.
• Emax: High Energy Ball Mill — Retsch: High energy ball mill that combines high frequency impact with intensive friction, reaching a final fineness below 80 nm. Integrated water cooling and temperature control allow long grinding runs without the sample overheating, which is what normally limits nanoscale grinding. It is used for nano grinding, mechanical alloying and colloidal milling.
• CryoMill — Retsch: Mixer mill that cools the grinding jar continuously with liquid nitrogen to minus 196 degrees Celsius during grinding, so elastic and temperature sensitive material becomes brittle enough to fracture. Cooling runs before and throughout the cycle, and the jar is cooled rather than the sample being immersed, so the sample stays dry.
• MM 400: Mixer Mill — Retsch: Multipurpose mixer mill for dry, wet and cryogenic grinding of small sample quantities, and for cell disruption in reaction vials. Two jars oscillate radially at 3 to 30 Hz, and typical grinding times are 30 seconds to 2 minutes. It also handles mixing and homogenisation, which makes it a general purpose bench unit.
• MM 500 control: Mixer Mill — Retsch: High energy mixer mill with jar temperature control from minus 100 to 100 degrees Celsius, so the thermal conditions of a grinding or mechanochemical run can be set and held. It runs at up to 30 Hz for dry, wet and cryogenic grinding, and reaches a final fineness of about 0.1 µm.
• MM 500 nano: Mixer Mill — Retsch: Mixer mill developed for producing particles in the nanometre range from batches of up to 2 x 45 ml, reaching about 0.1 µm. It supports dry, wet and cryogenic grinding as well as mechanochemistry and mechanical alloying, and the larger jar volume distinguishes it from the MM 400.
• MM 500 vario: Mixer Mill — Retsch: Mixer mill with six grinding stations, so up to 50 samples can be processed in one run when adapter racks are used. It is aimed at laboratories with a high sample count rather than a single demanding sample, and covers mechanochemistry, homogenisation, size reduction and cryogenic grinding.
• PM 100: Planetary Ball Mill — Retsch: Single station planetary ball mill in which the jar rotates about its own axis on a counter rotating sun wheel, so grinding balls are driven across the jar wall by Coriolis forces. That produces high pulverisation energy and short grinding times, down to below 1 µm and to 0.1 µm for colloidal grinding.
• PM 200: Planetary Ball Mill — Retsch: Two station planetary ball mill for grinding two samples in parallel under identical conditions, or one sample with a counterweight. Jar sizes go up to 125 ml and the mill reaches below 1 µm, and 0.1 µm for colloidal grinding. Input energy can be measured, which supports mechanochemical work.
• PM 300: Planetary Ball Mill — Retsch: Two station planetary ball mill taking jars up to 500 ml, with a higher sun wheel speed and a centrifugal acceleration of 64 g. The larger batch volume and higher energy input suit mechanochemistry and co-crystal screening as well as conventional fine grinding.
• PM 400: Planetary Ball Mill — Retsch: Floor standing planetary ball mill with four grinding stations, taking a maximum batch of 4 x 220 ml, or eight samples with stacked jars. The speed ratio can be set to 1 to minus 2, 1 to minus 2.5 or 1 to minus 3, which changes the balance between impact and friction in the grinding action.
• TM 300: Drum Mill and Bond Index Tester — Retsch: Drum mill for dry and wet grinding of soft, hard, brittle and fibrous material, with drums from 5 to 43.3 litres. Fitted with the ball or rod module it also serves as a Bond Index Tester, which is the standard way to quantify the grindability of ores and minerals ahead of plant design.
• TM 500: Drum Mill — Retsch: Large drum mill for sample volumes up to 35 litres, grinding by friction and impact down to about 15 µm. It is the unit to use when a single sample is too large for a planetary or vibratory mill, for example in cement, mining and ceramics laboratories.
• XRD-Mill McCrone — Retsch: Micronising mill developed specifically for preparing samples for X-ray diffraction. Forty eight cylindrical grinding elements arranged in the jar apply a gentle grinding action that reduces particle size below 1 µm while preserving the crystal lattice, which is what a diffraction measurement depends on.
• GrindControl: Pressure and Temperature Measuring System — Retsch: Measuring system that records pressure and temperature inside a sealed grinding jar during a run and transmits the data wirelessly. It turns a ball mill into an instrument for studying what actually happens during grinding, which matters for mechanochemical reactions where gas is evolved or consumed.
• BRILLANT 230: Cut-off Machine — QATM: Wet abrasive cut-off machine with manual wheel feed for sectioning metallographic samples up to 110 mm diameter. The aluminium body has openings on both sides so long parts can be passed through the cutting chamber, and the chamber itself is large enough for a range of clamping arrangements.
• Qcut 250 M: Cut-off Machine — QATM: Manual wet abrasive cutting machine in which the hood folds inwards on opening, leaving the whole cutting chamber accessible. A round window gives a clear view of the cut in progress. It takes wheels up to 250 mm and samples up to 90 mm diameter for short lengths.
• Qcut 250 A: Cut-off Machine — QATM: Semi-automatic abrasive cut-off machine with an automatic X axis, so it can perform pulsed cuts and oscillation cutting on large pieces as well as manual traverse cuts by hand wheel. An optional automatic cross table allows serial cutting, and the axes are monitored by travel measurement during setup and operation.
• Qcut 350 A: Cut-off Machine — QATM: Automatic wet abrasive cut-off machine for samples up to 135 mm diameter, with a low contact cutting function that reduces the thermal load on the specimen. Software features include automatic touch detection and multi-position processing, and it is used on composites and electronic assemblies as well as metals.
• Qcut 500 A: Large Cut-off Machine — QATM: Floor standing automatic cut-off machine for large components up to 190 mm diameter, with a highly dynamic axis drive and automatic traverse and chop cut functions. Feed rate is adjustable across a wide range so contact pressure can be tuned to the material.
• Qcut 600 A: Large Cut-off Machine — QATM: The largest cut-off machine in the QATM range, taking wheels up to 600 mm and workpieces up to 244 mm diameter. Automatic travel and cross feed allow low contact cutting of heavy components without repositioning by hand, and the working chamber is sized for the parts that come with that capacity.
• Qcut 200 A: Precision Cut-off Machine — QATM: Precision cut-off machine with up to three automatic axes for sectioning small and delicate samples where kerf position matters to a few micrometres. Cross feed resolution is 0.001 mm, which suits electronic components, coatings and thin sections rather than bulk metallography.
• Qtool Series: Quick Clamping Tools — QATM: Quick clamping tools that hold the specimen securely on the cutting table without slow screw adjustment between samples. Correct clamping is what prevents the specimen shifting mid cut, which would damage the wheel and ruin the section, so it is a functional part of the cutting process rather than an accessory.
• Qpress 40: Hot Mounting Press — QATM: Fully hydraulic hot mounting press with water cooling, embedding metallographic specimens in thermosetting resin. Heating and cooling times, temperature and pressure are set on an industrial touchscreen, and mould cylinders are available in several round and rectangular sizes. Advanced software adds one button operation and controlled fine dust extraction.
• Qpress 50: Hot Mounting Press — QATM: Hot mounting press in the same fully hydraulic, water cooled family as the Qpress 40, sized for the larger mould diameters. It uses the same closure system, which is designed so the mould assembly opens and closes cleanly over long service.
• Qmount: UV Mounting Device — QATM: Ultraviolet curing mounting device that sets the embedding resin with UV light instead of heat and pressure. Because there is no thermal cycle, it suits specimens that would be altered by hot mounting, and cure times are short compared with conventional cold mounting resins.
• Qpol M1 / M2: Manual Grinding and Polishing Machine — QATM: Manual single wheel (M1) and twin wheel (M2) grinding and polishing machines for laboratories preparing specimens by hand. They accept the Qpol GO head as a retrofit, so a laboratory can start manual and add semi-automatic preparation later without replacing the base machine.
• Qpol GO: Grinding and Polishing Head — QATM: Grinding and polishing head that converts a manual Qpol machine into a semi-automatic one. Single pressure and preparation time are set with rotary controls on the head itself, and the working area is lit and left visible by the slim housing.
• Qpol GO 1 / GO 2: Grinding and Polishing Machine — QATM: Automatic single wheel (GO 1) and twin wheel (GO 2) grinding and polishing machines that can run in single pressure or central pressure mode. Single pressure loads each specimen individually, which suits mixed hardness samples; central pressure loads the whole holder, which is faster for identical specimens.
• Qpol PLUS 1 / PLUS 2: Grinding and Polishing Machine — QATM: Automatic single wheel (PLUS 1) and twin wheel (PLUS 2) grinding and polishing machines with a higher performance head than the GO series, taking sample holders up to 185 mm diameter in central pressure mode. Specimens up to 50 mm diameter can be prepared, six at a time under single pressure.
• Saphir 550 / Rubin 520: Grinding and Polishing Machine — QATM: Grinding and polishing machine pairing a Saphir 550 base unit with a Rubin 520 preparation head. The head carries the sample holder and applies the load while the base drives the working wheel, so head and base can be specified to suit the throughput a laboratory needs.
• Saphir 560 / Rubin 520: Grinding and Polishing Machine — QATM: Grinding and polishing machine combining a Saphir 560 base unit with a Rubin 520 preparation head, the larger base in the Saphir line. As with the 550 combination, the head applies specimen load and the base drives the working wheel under programmed control.
• Qpol XL: Grinding and Polishing Machine — QATM: Large format grinding and polishing machine taking 300 mm and 350 mm working wheels and sample holders from 159 mm to 204 mm diameter. Both wheel and holder speeds are variable, which allows the removal rate and surface finish to be set independently.
• Qpol Vibro: Vibratory Polisher — QATM: Vibratory polisher that produces specimen surfaces with almost no residual deformation, by letting the sample move under its own weight on a vibrating cloth rather than being pressed against it. That matters for electron backscatter diffraction, atomic force microscopy and nanoindentation, where a deformed layer would mask the result.
• Qgrind XL: Planar Grinding Machine — QATM: Automatic planar grinding machine for the first, heavy removal step in specimen preparation. A ForceControl function measures removal electronically so the depth ground away is reproducible, and different grinding modes let the machine be set for maximum removal or for surface quality.
• Qetch 100 M: Electrolytic Polishing and Etching Machine — QATM: Manual electrolytic polisher and etcher that removes material by anodic dissolution rather than abrasion, giving a deformation free surface on metals that smear or work harden under mechanical polishing. The same unit performs electrolytic etching to reveal the microstructure.
• Qetch 1000: Electrolytic Polishing and Etching Machine — QATM: Electrolytic polishing and etching machine with programmable parameter control, so voltage, current and time can be stored per material and recalled. It covers the same anodic dissolution process as the Qetch 100 M with the reproducibility that stored settings give.
• Qness 10 / 60 M: Micro Hardness Tester — QATM: Manual micro hardness tester covering Vickers, Knoop and Brinell, with Rockwell as an option. Force is applied electronically and the test sequence runs automatically once the indent position is set. An eight position motorised turret carries up to three testing modules and seven lenses, so the tester doubles as a metallurgical microscope.
• Qness 10 / 60 A+: Micro Hardness Tester — QATM: Fully automatic micro hardness tester with a motorised XY cross slide, so hardness traverses and case depth profiles run without operator intervention. Positioning accuracy is 2 micrometres and the table travel can be extended to 300 by 150 mm for larger specimens.
• Qness 60 A+ EVO: Micro Hardness Tester — QATM: The EVO generation of the automatic micro hardness tester, with positioning accuracy improved to 0.2 micrometres. That resolution matters for closely spaced indent series such as case hardening depth measurements, where indent spacing rules limit how near indents may be placed.
• Qness 150 CS: Rockwell Hardness Tester — QATM: Compact Rockwell hardness tester with a C shaped frame, a fixed test head and a spindle that raises the specimen to the indenter. Force is applied electronically and the sequence runs automatically, with results shown on a 7 inch touchscreen. It complies with DIN EN ISO 6508 and ASTM E-18.
• Qness 150 CSA+: Rockwell Hardness Tester — QATM: Rockwell hardness tester with a fully automatic XY slide, combining the speed of a dedicated Rockwell machine with automated series testing. It suits parts of identical test height where a defined pattern of indents is required, and single tests can still be run manually.
• Qness 60 / 150 RCS: Rockwell Hardness Tester — QATM: Production line Rockwell hardness tester with a test cycle under two seconds, controlled by a Siemens S7 with a 4 inch touch display. It is built to be integrated into a production line for in-process hardness checking, with results output over an RS232 interface.
• Qness 200 CS: Macro Hardness Tester — QATM: Compact universal macro hardness tester with a five position turret carrying indenters and lenses. The fixed head and moving spindle arrangement gives a 250 mm test height with a 238 mm throat, so reasonably large parts can be tested without a special fixture.
• Qness 250 / 750 / 3000 C and CS EVO: Universal Hardness Tester — QATM: Universal hardness testers covering Brinell, Vickers, Rockwell, Knoop and plastics methods, in three force classes up to 3000 kg. The C shaped frame with fixed head and moving spindle gives a 395 mm test height, and an eight position tool changer is available in place of the standard two positions.
• Qness 250 / 750 / 3000 E EVO: Macro Hardness Tester — QATM: Macro hardness testers with an extra large fixed test table and a motorised test head, so very large components can be tested without lifting them onto a spindle. Test height reaches 510 mm and the table measures 584 by 450 mm, which puts heavy fabricated parts within reach.
• Qness 250 / 750 / 3000 A+ EVO: Fully Automated Macro Hardness Tester — QATM: Fully automated macro hardness testers with three axis control, so specimens of differing test height can be measured in one run without refixturing. A Jominy sample holder with test module is available as an option for end quench hardenability testing.
