Flammable gas detector (or LEL gas detector) is a line of analyzers of combustible gas concentrations in the environment to warn and alarm when the environment reaches the combustible and explosive threshold causing danger to people and property of business.
Combustible gas and O2 gas present in the environment can react with each other to cause fire and explosion. This is very dangerous for people, so it is necessary to take precautions before that happens. Therefore, the LEL gas detector is a necessary device to monitor the hazards of flammable gas
Manufacturers use sensor technologies to detect LEL gas such as: catalytic sensor and IR infrared sensor.
However, IR is rarely used because of the very high cost, but the accuracy is also very high.)
Depending on the manufacturer, the gas detector can measure the following gases: Hydrogen, Methane, Propane, n-Butane, n-Pentane, n-Hexane, n Octane, Methanol, Ethanol, Isopropyl Alcohol, Acetone, Ammonia, Toluene, Gasoline (Unleaded)…
