CHI111 is the silver / silver chloride reference electrode in the CH Instruments range, closed with a porous Teflon tip. The accessory list pairs it in one figure with the CHI112 non-aqueous reference electrode. It provides the reference half of a three electrode arrangement built from the working and counter electrodes on the same list.

For non-aqueous work CH Instruments list the CHI112, a silver / silver ion reference electrode fitted with a porous Teflon tip. The published note states that the Ag+ solution, typically 10 mM, has to be made up from the supporting electrolyte and AgNO3, neither of which is supplied, and then loaded into the reference compartment with a syringe that is also not supplied. Instructions are shipped with the components. It shares a figure with the CHI111 aqueous reference electrode.
This platinum microelectrode is published with a 25 micron diameter and is the larger of the two platinum microelectrode sizes CH Instruments offer. It is listed alongside CHI105, CHI106 and CHI107 in the Au/Pt microelectrode group and appears in the shared group photograph.
CHI115 is a platinum wire counter electrode, published with its own figure on the CH Instruments accessory list. It supplies the counter electrode in cells assembled from the working and reference electrodes in the same range.
