Portable Data Storage Function 0-100%LEL CH4 Methane Combustible Gas Detector
The flammable gas is the most common hazardous gas in mines –
especially in coal mines, where large pockets may be present.
Methane, one of the combustible gas which is lighter than air,
tends to rise to the ceiling of a mine or tunnel leaving it
virtually undetectable to the senses. Methane can cause injury or
death by asphyxiation, when it is in high concentrations, or by
exploding when ignited by a flame or spark. The sensors inside the
YuanTe detectors can detect up various combustible gas, which can
display accurate data.
