A toxic gas detector is a device that is designed to identify hazardous levels of gases and vapors within a workplace or area. Typically, the devices are programmed with a pre-set level and when the readings reach that specific level an alarm will activate. These devices can be portable or fixed in the area where they are used. They are often triggered by electrochemical sensors.

These systems can detect a variety of different chemicals, vapors and gases in industrial environments. They are used to monitor safety hazards such as anhydrous ammonia (NH3) in food & beverage plants, carbon monoxide in coal mines and hydrogen sulfide at wastewater treatment facilities. They can also be used to identify combustible gas dangers including acetylene, propane and butane in welding environments.

Upon detection of an unsafe level of gas, the sensors inside a toxic gas detector will immediately activate visual and audible alarms, depending on the type of sensor. These alarms can then send a digital or analog signal to a control room or actuate local relays for the operation of alarm safety devices such as horns, fans and valves.

Toxic gas detectors are essential in industries that use corrosive, asphyxiant and combustible chemicals. They can also be found in applications where there are potentially dangerous pressurized leaks such as LNG plants and water treatment facilities. Toxic gas detectors offer a range of different features, such as display units with non-intrusive calibration and local event logging capabilities, to help businesses improve safety standards in the workplace.
