CH4/C2H4/C3H8/C4H10-D3C-H 5V Sensor Module
CH4-D3
CH-D3 series are an ultra-small dual channel methane/ethylene/propane/butane gas modules that adopt the principle of the non-dispersive Infrared (NDIR). It can be useful in various industries, as it provides excellent calibration algorithm, long-term stability and easy maintenance.
