Winsen ME3-O3 Gas Sensor

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

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