Manufacture ME4-O3-E4 Ozone Gas sensor electromedical industrial gas sensor

ME4-O3-E4 nitrogen dioxide 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.

Features

High precision, high sensitivity, wide linear range, good anti-interference ability, strong resolution.

Main applications

It widely used in urban atmospheric environmental detection, enterprise environmental detection,factory pollution gas detection, emergency environmental assessment detection.
