Fixed Hydrogen Sulfide Sensor

The fixed hydrogen sulfide detector utilizes an electrochemical sensor to measure the concentration of hydrogen sulfide gas in the air. When hydrogen sulfide reacts with the electrolyte inside the sensor, it generates an electrical current signal, which is processed by the circuitry and converted into a concentration reading. It is used for continuous monitoring in locations such as chemical plants and wastewater treatment facilities, triggering audible and visual alarms when levels exceed the standard.
Selection
When selecting, consider that the detection range should cover the concentration of the application scenario, the explosion-proof rating should match the installation area requirements, the sensor lifespan should influence the replacement cycle, the output signal should be compatible with the existing control system, and environmental adaptability should meet temperature and humidity conditions.
