Type:Chlorine sensor

Illustrate:It can online monitor the residual chlorine concentration for the drink water ,water disinfection in industrial process .

CXNS-70 Chlorine sensor
·Application
It can online monitor the residual chlorine concentration for the drink water ,water disinfection in industrial process . It can also used in the swimming pools where the place need to measure the residual chlorine concentration.
·Measuring principle
CXNS-70 type oxygen electrode is a diaphragm polarographic (clark) sensor . It is  consisted of cathode , anode , electrolyte and a layer of gas permeability diaphragm on the cathode . The measured residual chlorine diffuse to the cathode through diaphragm .The proper polarization voltage between the cathode and the anode ,which can deoxidize the residual chlorine on the cathode . These chemical actions proportional to the residual chlorine which is in the measured medium .·Feature
★  Sensitive response ,good stability
★  Do not need to replace the diaphragm and the electrolyte .
★  Suitable for variety of waste water , the diaphragm is difficult to be damaged, anti-pollution .
