Air Hydrogen Sulfide Detector

The air hydrogen sulfide detector measures the concentration of hydrogen sulfide in the air using an electrochemical sensor. Inside the sensor, redox reactions generate an electrical current signal, which is converted by the circuit into a concentration reading. It is used for leak monitoring and safety protection in workplaces such as chemical plants and wastewater treatment facilities.
Selection
When selecting, consider a detection range covering 0-100 ppm with a resolution of 1 ppm. Explosion-proof certification and IP protection rating are required. Check the sensor lifespan and calibration cycle. Pay attention to response time and alarm methods. Evaluate data logging capabilities and power endurance.
