Product Description:
ME4-O3-E4 ozone gas sensor is constant potential electrolysis type. Oxidation-reduction with ozone and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge to current that is in direct proportion to the ozone concentration. The fourth auxiliary electrodes is used to compensate the zero current, characteristic of strong signal level and low zero current.
