012127 is the carbon interdigitated array electrode CH Instruments list alongside the gold and platinum versions. The published datasheet quotes the same array for all materials, 65 pairs of bands 10 micron wide and 2 mm long at a 5 micron interval. It connects through the 011066 cable kit and is handled with the care the datasheet asks for quartz glass electrodes.

Part 012167 is the silver / silver chloride reference electrode CH Instruments list for the CHI140A spectroelectrochemical cell, published in the CHI140A kit sheet as the RE-1B reference electrode. The CHI140A ships without a reference electrode, so this part or the non-aqueous 012171 has to be ordered with it.
The platinum version of the interdigitated array electrode, catalogued by CH Instruments as 012126. Its published geometry matches the rest of the IDA family: 65 pairs of generator and collector bands of 10 micron width, 5 micron interval and 2 mm length. Redox cycling between the interdigitated bands is what raises the measured signal, and the 011066 cable kit provides the connection.
SE101 is a screen printed carbon electrode in the single working electrode configuration, published with a 3 mm working diameter and a working area of 0.071 cm2 for aqueous solutions. CH Instruments list it in packs of 40 and describe the screen printed range as disposable or reusable, needing no electrode polishing, open to chemical modification, and extendable in applicability after preanodisation. It sits between the 5 mm SE100 and the 1.5 mm SE102 in the published single electrode series.
