MIX8421 0-20ppm Electrochemical Sulphur Dioxide/SO2 Toxic Detection Sensor

MIX8421 Electrochemical 0-20ppm Sulphur Dioxide (SO2)Gas Sensor For Industrial Toxic Detection

Principle Introduction:


MIX8421-SO2 electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.



* High selectivity for SO2 gas

* High accuracy 

* Linear output 

* Environmental protection design

* Wide linear range

* Good anti-interference ability

* Excellent repeatability and stability




* Industrial SO2 gas monitors leakage detection

* industrial and environmental protection fields
