Abstract

A pH sensing electrode is provided in which an insulted copper conductor is cleaved to provide an exposed clean end surface, and an antimony coating is sputtered or evaporated thereonto. The pH sensing is achieved by measuring the voltage difference between the said electrode and a silver reference electrode immersed in the same material. The electrode finds application, for example, as a catheter for measuring the pH value of bodily fluids.
