Pentoxide which coated on the sensor meet the water in the sample gas to form a weak potential electrolysis, 2P2O5+3H2O=4H3PO4, so detect the trace water content in the sample gas. The performance of Smart20 is good, rarely require maintenance, and the sensor with precious metals has very long life. ppm level measurement for the moisture content in the acidic and neutral gas to ensure the production.
Smart20 can be automatically calibrated in the range of 0 to 500ppm without switching operation (The resolution is 0.1ppm). The sensor can automatically identify and detect the change in activity of the electrolyte layer, to achieve rapid detection of the coating.
