Methane (CH 4) is a colorless, odorless gas with a wide distribution in nature. Methane is known chiefly as being the principal component of natural gas, which is a mixture containing about 75% methane (CH 4), 15% ethane (C 2 H 6), and 5% other hydrocarbons, suh as propane (C 3 H 8) and butane (CH 4 H 10). The principal use of methane is as a fuel.

The MQ4 methane gas sensor is extremely used for detecting gas leakage at home or in industries like Methane (CH4) CNG Gas. This gas sensor is highly responsive in very little time, so based on the sensitivity requirements; it can be adjusted through a is an analog output sensor, used like a CNG (compressed natural gas) sensor within the series of MQ sensors.
MQ4 gas sensor has high sensitivity to methane, also has antiinterference to alcohol and other gases. It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector. Tips:For more parameter information, please refer to the latest manual provided by salesman. 26Ω±3Ω (room tem.)
17/6/2016· Documents. This is a simpletouse compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ4 can detect natural gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor''s output is an analog resistance.
Figaro offers a wide range of gas sensors and modules with different principles such as MOS type, catalytic type and electrochemical type.
Methane. Methane (CH4) is the main constituent of natural gas. The abundance of methane makes it an attractive fuel. In addition, it is useful in many industrial processes. GasLab offers methane sensors capable of measuring up to methane gas.
30/12/2018· Why laser methane gas sensor has a longer calibration cycle or even calibration free? Laser type methane sensors employ the most advance and stable semiconductor technology, which has an advantage in longterm, stable and reliable working state. Only one time adjustment at the factory is needed then calibration free during its life time.
