ME3-PH3 Phosphine Electrochemical Sensor Industrial Gas Detection 0-10ppm

Phosphine electrochemical sensor ME3-PH3 Work according to the principles of electrochemistry, electrochemical oxidation process utilizing test gas in the electrolytic cell working electrode, through the electronic circuit of the working electrode and reference the cell constant potential in an appropriate electrode, can occur in the potential electrochemical oxidation gas to be measured, due to the oxygen in the oxidation and reduction reactions arising from the Faraday current is very small, negligible, so the current is proportional to its concentration test gas generated by electrochemical reaction and follow Faraday\’s law. Thus, by measuring the current size can determine the concentration of the test gas.
