1、 Introduction to Infrared Methane Sensor IRM-AT:
Alphasense is a professional manufacturer of gas sensors in the UK. The newly developed small-sized infrared CH4 gas sensor uses non dispersive infrared (NDIR) technology to detect gases. It detects the presence and concentration of target gases based on their different absorption rates of infrared spectra at different concentrations, and is not easily affected by harsh on-site environments. Adopting 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
