Principle Introduction:
Winsen Electronics, manufacture and provide ozone/ O3 gas sensor, based on the electrochemical principle, industrial and environmental protection fields.
ME3-O3 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.

Applications :
Ozone gas sensor, O3 sensor are widely used in industrial and environmental protection fields.
ZE11 ozone gas sensor module available as well.
