product details
ME3-C2H4Based on the principle of electrochemistry, a type of electrochemical gas sensor utilizes the gas to be tested to undergo an electrochemical reaction on the working electrode in an electrolytic cell. The current generated by the gas during the electrochemical reaction is proportional to its concentration and follows Faraday's law. Therefore, the concentration of the gas to be tested can be determined by measuring the magnitude of the reaction current.
Sensor characteristics
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference ability, excellent repeatability and stability.
Main applications
Widely suitable for the detection of ethylene in industry and environmental protection.
