The Toxic Gas Alarm consists of a detector and an alarm control unit. It is widely used in petrochemical industries such as petroleum, fuel gas, chemical engineering and oil depots where toxic gases may exist. It is designed to detect gas leaks in hazardous indoor and outdoor locations, serving as a critical instrument for ensuring production and personal safety.

When toxic gas is present in the detected area, the detector converts the gas signal into a voltage or current signal and transmits it to the alarm device. The instrument displays the gas concentration as a percentage of the Lower Explosive Limit (LEL) of the toxic gas. When the toxic gas concentration exceeds the preset alarm threshold, an audible and visual alarm will be triggered to prompt on-duty personnel to take timely safety measures, thereby preventing combustion and explosion accidents.

The S4100 Combustible Gas Alarm adopts a catalytic sensor and is suitable for continuous monitoring of flammable gas leaks in environments across various industries such as chemical plants, coal chemical industries, and petrochemical facilities.

Equipped with a microprocessor system and push-button operation, the alarm supports functions such as calibration, zero-point adjustment, and high/low alarm value settings. Its power supply module includes under-voltage indication and protection, and the device features a compact structural design.
