NonDispersive Infrared, NDIR, Carbon Dioxide Sensors ...

Mar 21, 2017· NDIR CO2 Sensor. Nondispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas.
