Industrial pH Electrode - Armor Casing [Discontinued] _MB_ROBO Stickvise is designed with simpleThis pH combination electrode is made of sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response, good thermal stability. It has the good reproducibility, difficult to hydrolysis, and basically eliminate the alkali error . In 0 to 14pH range,the output voltage of the electrode is linear. The reference system which consist of the Ag AgCl gel electrolyte salt bridge has a stable half cell potential
