Infrared methane sensor IRM-AT detailed introduction:

一. Introduction of infrared methane sensor IRM-AT:

The British company Alphasense is a manufacturer specializing in the production of gas sensors. The newly developed small-size infrared CH4 gas sensor uses non-dispersive infrared (NDIR) technology to detect gases. The absorption rate of the infrared spectrum varies according to different gases at different concentrations. To detect the presence and concentration of the target gas is not easily affected by the harsh environment on site. Using dual-channel sampling technology, it can self-suppress zero drift. It has the characteristics of long calibration cycle, strong anti-interference ability, high precision, high reliability and long service life.
