Product Description:
4H2S-AS three-electrode electrochemical hydrogen sulfide sensor
Features:
Hydrogen sulfide gas sensor is a device used to monitor the concentration of hydrogen sulfide gas in the ambient air. The semiconductor technology hydrogen sulfide gas detector is designed to monitor the concentration of hydrogen sulfide gas in ambient air, and its measurement range is from 0-20/50/100ppm for standard models (adjustable at the job site) to 10,000ppm for high measurement range models. The product uses solid metal oxide semiconductor sensing technology. The sensor consists of two sheets: one is a heating sheet and the other is a gas-sensitive sheet that is sensitive to hydrogen sulfide gas. Both sheets are mounted on a silicon chip in a vacuum coating. The heating plate raises the operating temperature of the gas sensitive plate to a level that can react to hydrogen sulfide gas. There are metal oxides on the gas sensitive sheet, which can dynamically display the change of hydrogen sulfide gas concentration.
