About industrial gas leak detector:
Gas detector is a safety device that detects and monitors various toxic, combustible and flammable gasses in an area and which can also register a decrease in ambient oxygen
Gas detectors have a variety of industrial and governmental applications, such as in fire and rescue, mining, construction, petroleum refineries, tanneries, sewage treatment facilities and paper mills
Due to different needs, gas detector can be divided into portable or stationary, portable gas detectors are typically used to monitor the air around personnel, are worn on clothing or on belts or harnesses, and are powered with rechargeable or disposable batteries
Stationary gas detectors are typically powered electrically and mounted near the process area of a plant or control room
They also require periodic service, testing and calibration
