Flammable Gas Online Monitor

The online combustible gas monitor detects changes in the concentration of combustible gases in the air through catalytic combustion or infrared principles. The sensor converts gas concentration into electrical signals for real-time display and alarm. It is used for continuous safety monitoring in places such as chemical plants and gas stations where there is a risk of gas leakage.
Selection
When selecting, ensure the gas type to be measured matches the sensor type, consider the explosion-proof rating and compatibility with the on-site environment, verify that the detection range and alarm thresholds meet safety standards, confirm that the output signal can interface with the existing control system, and pay attention to the sensor lifespan and calibration cycle to maintain long-term stable operation.
