Detailed Description
Model NO.:IRM300 Output:Analog Sensor Usage:Pressure Sensitive Sensor Theory:Mems Material:Mixture Adopting Ndir Principle:Single Light Source Dual Channel Detector:Microprocessor Good Selectivityhigh Sensitivity,:Long Life and Independence to O2 Indoor Air Monitoring,:Agriculture Monitoring Export Markets:Global Introduction IRM300 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 300 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. IRM300 is suitable for the test in flexible occasion, and its calibration possibility in clean air makes it a good choice in portable instrument, for example educational apparatus. All the products can be customized according to your requirement.
