Common knowledge of H2S
How does a hydrogen sulfide sensor detect hydrogen sulfide gas
Hydrogen sulfide sensors usually use electrochemical principles, utilizing three electrodes to electrochemical gas sensors, When hydrogen sulfide gas enters the sensor, an oxidation reduction reaction occurs on the electrode, thereby producing an electrical signal proportional to the concentration of hydrogen sulfur sulfide. The concentration of the hydrogen sulfate is determined by the detection and treatment of the electrical signal.
Does the hydrogen sulfide sensor need to be calibrated regularly
Need. In order to ensure the accuracy and reliability of sensor measurement, it is usually necessary to regularly calibrate the hydrogen sulfide sensor, and the calibration cycle is generally six months to one year, which can be adjusted appropriately according to factors such as the use environment and frequency.
What is the detection range of the hydrogen sulfide sensor
The detection range of different models of hydrogen sulfide sensor is different, generally the common detection range is between 0-100ppm (one millionth) to 0-10,000ppm, and the sensor with suitable detection range can be selected according to the specific use scene and demand.
Application Scenarios
Industrial production
Waste gas emission monitoring: Conduct real-time monitoring of industrial waste gas emissions to ensure that waste gases meet emission standards and reduce pollution to the environment.
