Combination pH measuring cell with integrated temperature sensor

摘要

A combination pH measuring cell comprises a pH glass electrode with internal buffer 1 and pick-up system 2, a pick-up system for the reference electrode 3, a reference electrolyte 4, a membrane 5 and also a temperature sensor 6, which are all combined in a single shank, and a connection of the temperature sensor 6 is identical to the electrical terminal of the reference electrode of the pick-up system of the reference electrode 3. The connection cable comprises a triaxial cable 9. The cable may be connected to the electrode permanently or by means of a suitable plug connection, the screen 11 being provided jointly for the reference electrode signal and for the connection of the temperature sensor 6 and the screen 12 for the temperature sensor 6 (Figure 1).
