Halogen gas alarm

Halogen gas alarms detect the concentration of halogen gases in the air through electrochemical or semiconductor sensors. When the gas reacts with the sensor, it causes a change in the electrical signal, triggering the alarm. These alarms are used to monitor leaks of gases such as fluorine, chlorine, bromine, and iodine in laboratories, chemical plants, and other facilities to ensure personnel safety.
Selection
When selecting a halogen gas alarm, consider the types of gases to be detected, the measurement range, and sensitivity. Determine the explosion-proof rating and protection standards based on the usage environment. Check the sensor lifespan and calibration cycle. Ensure that the display and alarm methods meet on-site requirements. Verify product certifications and after-sales services.
