In pH measuring applications such as hydrofluoric acid, where glass electrodes have a short life, antimony electrodes are usually used. There are many makes of antimony electrode sensors available but all except one make have difficulty in compensating for changes in temperature. The GLI antimony electrode sensor uses a patented differential system to solve this problem.
Antimony electrodes have a temperature coefficient of 1 to 3 mV per ºC, increasing with pH, compared to glass electrodes that have a temperature coefficient of about 0,4 mV per ºC. Because the antimony electrode does not have symmetry with conventional reference electrodes, temperature compensation is difficult. This problem is largely eliminated in the patented GLI sensor shown which uses an antimony electrode as the standard electrode as well as for the active process electrode and both measure the pH differentially with respect to a third ground electrode.
