Introduction of 1. infrared methane sensor IRM-AT:
British Alphasense company is a professional manufacturer of gas sensors. The newly developed small-size infrared CH4 gas sensor uses non-dispersive infrared (NDIR) technology to detect gas. According to the absorption rate of infrared spectrum under different concentrations of different gases, the existence and concentration of target gases are not easily affected by the harsh environment on site. A dual-channel sampling technique is used to self-suppress zero drift. It has the characteristics of long calibration cycle, strong anti-interference ability, high precision, high reliability and long service life.
