Product description: Flammable gas detector - Benetech GM8800B
The Benetech GM8800B is a professional flammable gas detector designed for detecting gas leaks in residential and industrial installations. The device utilizes a highly sensitive semiconductor sensor that can detect even low gas concentrations, down to 50 ppm for methane. The detector responds with an audible signal and LEDs , allowing for quick location of the leak source. The flexible measuring neck, nearly 38.5 cm long, allows for inspection of hard-to-reach areas such as pipe joints, valves, and cabinet interiors. Simple operation, auto-calibration, and sensitivity adjustment make the GM8800B suitable for both professionals and home users.

The detector detects, among others: natural gas, propane, butane, methane, propanol, ethanol, ammonia, carbon monoxide, gasoline vapors and hydrogen sulphide.

What gases does the Benetech GM8800B detector detect?
The Benetech GM8800B gas detector detects a wide range of flammable, toxic, and explosive gases that can pose a health and safety risk. The device responds at low concentrations – sensitivity is 50 ppm for methane . Detectable substances include natural gas, methane, propane, butane, propanol, ethanol, ammonia, hydrogen sulfide, carbon monoxide (CO) , as well as gasoline, kerosene, solvent, paint, and smoke vapors . The GM8800B also detects water vapor and combustible gas mixtures (LEL) , making it a highly versatile tool for gas detection in various environments. This wide operating range makes the detector suitable for both residential gas installations and industrial inspections , service work, and laboratory research. It is suitable for situations where a traditional detector would not be able to detect all potential gas threats.
