Product features: 1.High measurement accuracy.Detect in PPM,tiny leakage warning is possible,to prevent any possible danger to the maximum extent,
2.Highly selective to gases.Only reactive to Methane(main content of Natural gas),or Propane(main content of petroleum gas),
3.Will not absorbed by alcohol,CO(carbon monoxide)and other combustible gases,
4.False or failure alarm will not happen because of temperature ,moisture,smoke, alcohol etc. affection,
5.Long life time,with 2 years warranty,the actual working time will be more than 5 years,
6.The detecting unit can be disassembled and wiped clean without any calibration,
7.Integrated switch control,remote communication function.

How Does It Work?
When the infrared laser beam is transmitted from the launch port some of the laser light is reflected by normal background such as brick, concrete, grass, etc., to the detector. This reflected light is collected and converted to an electrical signal that carries the information needed to deduce the relative methane concentration. This signal is processed so that methane concentrations can be reported in ppm-m. The laser has a maximum distance of up to fifty meters and is selective to methane only. It will not false alarm on other hydrocarbons.
