Introduction
Miniature NDIR CH4 gas sensor adopts advanced non-dispersive technology to detect and monitor CH4 concentration. It is with a heated infrared source inside a small chamber, in this case, the inside temperature of the gas sensor is much higher than the outside which can avoid condensing events and the high humidity influence .
Besides, the PCB inside the gas sensor is specially treated for corrosion protection. 

Features:
1.NDIR technology, with longlifespan
2.Diffusion sampling, compact size, easy handling
3.High precision, low power consumption, less maintenance
4.Self-compensation of temperature
5.Great resistance to moisture and other gases interference
6.Voltage output and RS232 output are optional
7.Good sensitivity and selectivity to CH4 gas

Applications
1.Mine, metallurgy, liquefied gas station, spray paint, petroleum, fuel gas transport etc.
2.In gas leakage detecting equipment in family and industry
3.Gas concentration meter.
4.Combustible CH4 gas leakage alarm or detection
