PPB level trace CO gas analyzer

Carbon monoxide analyzer is an infrared spectrum gas analyzer, using GFC, NDIR detection of CO concentration, the basic principle is through the carbon monoxide on 4.67um infrared absorption characteristics, with a photodetector to detect the intensity of absorbed light, the use of Beer-lambert law (Beer-Lambert), to find the concentration of carbon monoxide, The instrument measurement module and associated runner are installed in a sealed foam box, which guarantees constant temperature and no interference from the external environment, with higher accuracy and reliability, and minimal maintenance. Since the infrared absorption method is a nonlinear measurement technique, the instrument circuit needs to convert the original signal into a linear output. The instrument adopts a correction curve derived from the company's summary of CO characteristics for many years to linearly correct the output of the instrument to ensure that the instrument has correct linearity. It can be used to detect and evaluate the CO concentration in ambient air quality parameters.
