Cảm biến đo nồng oxy oxygen sensor ME3-O2

Product description
ME3-O2 electrochemical oxygen sensor
   ME3-O2 oxygen sensor works according to the principle of electrochemical primary battery, using the electrochemical reduction of the gas to be measured on the cathode of the primary battery and the oxidation process of the anode to generate current, and to be tested The current generated by the electrochemical reaction of gas is proportional to its concentration and follows Faraday's law. In this way, the concentration of the gas to be measured can be determined by measuring the magnitude of the current.
