Hydrogen Sulfide Concentration Sensor

The hydrogen sulfide concentration detector measures gas levels using an electrochemical sensor, which reacts with hydrogen sulfide to generate an electrical current signal. This signal is processed by the circuitry to display a numerical value. It is used to monitor hydrogen sulfide leaks in industrial environments, wastewater treatment facilities, and other locations to ensure personnel safety.
Selection
When selecting, consider whether the detection range covers the application scenario, confirm the sensor lifespan and calibration cycle, check if the explosion-proof rating suits the environment, evaluate response time and alarm methods, and compare maintenance costs and data recording functions across different brands.
