■ electrode characteristics
Sensitive response, high accuracy and good stability
Simple operation and small maintenance
Suitable for all kinds of media, the membrane is not easy to be damaged and anti pollution
■ measurement principle
Ts-280 residual chlorine electrode is a diaphragm polarographic sensor, which is composed of cathode, anode, electrolyte and a gas permeable film covered on the cathode
The residual chlorine in the measured solution diffuses to the cathode through the diaphragm
The appropriate polarization voltage between the cathode and the anode can reduce the residual chlorine on the cathode
These chemical reactions produce a current proportional to the residual chlorine in the measured solution

■ scope of application
It is suitable for on-line monitoring of residual chlorine concentration in disinfection and sterilization processes of drinking water and industrial process water, and it can also be used in swimming pools and other occasions where residual chlorine concentration needs to be measured
