The electrode is made of ph glass electrode and a reference electrode combined composite electrode, which is ph meter measuring sensor for measuring the concentration of an aqueous solution of h (ph value), it is widely used in various fields to be detected in the ph.

The PH electrode has a single cylinder that allows direct connection to the input terminal of a PH meter, controller, or any PH device which has a BNC input terminal. The PH electrode probe is accurate and reliable that can gives almost instantaneous readings.
