1、 Measurement principle

Selective response of hydrogen ion concentration changes in aqueous solution using glass electrodes, andAg/AgCl/ClReference electrodes are combined together in solution to form“electrochemical cell”By measuring the changes in its electromotive force, determine the properties of the solutionpHValue.SensorLytThe electrode adopts a gel or polymer electrolyte, and the concentration of the electrolyte itself changes very little, providing a continuous and stable reference potential.

2、 Typical applications

1、 Sensolyt 700 IQ: Ordinary water/sewage

2、 Sensolyt 700 IQ SWHigh salinity wastewater such as seawater

3、 ECAElectrode: mildly polluted wastewater

4、 SEAElectrode: The electrolyte is a solid polymer that is not affected byAgClInterference, strong anti pollution ability, suitable for severely polluted wastewater, emulsifiers and suspensions, protein and sulfide containing wastewater
