摘要：
A description of the portable CO, Non-dispersive infrared detector (NDIR) is presented. The apparatus system principle and structure, experimental test technique including the circuit design and a method for calculating the sensor output data are discussed. The total uncertainty (99% confidence limits) obtained is +/-10 ppm at concentration range from 10 to 2000ppm of CO2.
