Product information "Industrial pH Electrode - Armor Casing"


This 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 and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.

Q: How to use it in the Arduino water quality monitoring system?

A: This industrial pH electrode can directly work with the sensor board from Analog pH Meter Kit to produce a long-term PH monitoring. And the output voltage feedback is from 0 to 5v to indicate PH value from 0 to 14.


The electrode is suitable for all kinds of printing, circuit board factory, waste water containing chromium and other industrial and domestic sewage pH monitoring.
