Fixed hydrogen sulfide monitor

A fixed hydrogen sulfide monitor detects the concentration of hydrogen sulfide gas in the environment through an electrochemical sensor. When the gas comes into contact with the sensor, it generates an electrical current signal, which is then converted by the circuit into a concentration reading. It is used for continuous monitoring of hydrogen sulfide leaks in industrial settings to ensure operational safety. It is commonly installed in fixed areas where hydrogen sulfide is present, such as oil and gas facilities, chemical plants, and wastewater treatment sites.
Selection
When selecting, consider whether the detection range covers the on-site concentration requirements, confirm that the explosion-proof rating matches the regional standards, check the sensor lifespan and calibration cycle, evaluate the compatibility of the output signal with the existing control system, verify that the enclosure protection rating is suitable for the installation environment, and ensure the response time meets safety requirements.
