What is portable 4-in-1 gas detector?
In our daily life, we may encounter a variety of environmental gas problems:
Such as exhaust emissions from industrial production sites, urban air pollution, excessive gas concentration in agricultural greenhouses and so on.
In order to protect our health and quality of life, a device that can monitor the gas condition in the environment in real time - portable 4-in-1 gas detector becomes more and more important.

Today we're looking at infrared methane
GH-CH4
Infrared flammable gas sensor based on non-dispersive infrared(NDIR) principle,compared with the traditional principle of gas sensor has good stability, wide detection range, strong selectivity , no oxygen
dependence,strong anti-interference ability, long life, long maintenance cycle and other advantages, is the development trend of gas detection,can quickly replace the traditional principle of gas sensor.Widely used in the presence of methane and explosive gas.

Application:Petrochemical industry.Mine environmental monitoring、Methane concentration measurement、Municipal pipe network、Gas and gasoline leaks.
