Flammable Gas Monitor

Combustible gas monitors detect the concentration of flammable gases in the air through catalytic combustion or infrared absorption principles. When gases come into contact with the sensor, they cause changes in electrical signals, triggering audible and visual alarms if the concentration exceeds the set threshold. They are used for real-time safety monitoring in places such as chemical plants and gas stations where there is a risk of gas leakage.
Selection
When selecting, consider matching the sensor type to the gas being detected, ensuring the explosion-proof rating suits the on-site environment, and verifying that the response time meets safety requirements. Check the calibration cycle and maintenance costs. Fixed types are suitable for continuous monitoring in specific areas, while portable types are used for temporary inspections. Pay attention to sensor lifespan and protection ratings.
