Introduction
IRM202 is one of the general NDIR CO2 gas modules, which adopting NDIR principle, consists of patented light chamber, precise electric circuit and intelligent software. With the help of single light source, dual channel detector, and microprocessor, IRM 202 can perform the gas concentration signal in different ways. In this product, temperature compensation has been realized as well as the revision of the nonlinear relationship. It has all the advantages from NDIR products, such as good selectivity, high sensitivity, long life and independence to O2.
IRM202 is suitable for the test in flexible occasion, for example indoor air monitoring, agriculture etc.
All of our products can be customized according to your requirement.
