Stainless Steel pH Sensor ( RS485 and 4~20mA outputs)
This PH sensor adopts the glass electrode method. The measuring part consists of a glass indicator electrode and a reference electrode. By measuring the potential difference of the working cell composed of the indicator electrode and the reference electrode in the solution, the online monitoring of pH is realised.
