Explosion-proof Combustible Gas Alarm

The explosion-proof combustible gas alarm detects changes in the concentration of combustible gases in the air through built-in sensors. When the concentration reaches a preset threshold, it triggers audible and visual alarms and activates ventilation devices. The device features an explosion-proof structural design for its housing, preventing electrical sparks from igniting gases in hazardous environments. It is primarily used in workplaces such as petrochemical plants and spray painting workshops where flammable and explosive gases are present.
Selection
When selecting, confirm that the hazard level of the work area matches the explosion-proof rating. Choose catalytic combustion or infrared sensors based on the type of gas to be measured, taking into account the impact of environmental temperature and humidity on detection accuracy. For fixed devices, plan the wiring layout, while portable devices should prioritize battery life. Check whether the product features local audible and visual alarms and signal output functions, and conduct regular calibration and maintenance to ensure long-term stability.
