TH-2004B infrared absorption of carbon monoxide analyzer

TH-2004B infrared absorption of carbon monoxide analyzer

Introduction

This instrument adopts the non dispersive infrared absorption method. Basic working principle is: the CO to specific wavelength (4.6 microns) of infrared radiation absorptivity, its concentration and weaken the principle of infrared radiation is nonlinear sample gas. Testing method is: infrared from infrared light source in turn through the rotation of CO and N2 filters in the filter wheel, then the narrow-band interference filter into the light chamber. Through CO filter in the filter wheel infrared light is absorbed, not the light in the room to absorb the CO in sample gas to form a fixed light intensity of reference beam, by N2 filters in the filter wheel, infrared don't get sucked into room and in the light sample gas, the sample gas absorption of infrared radiation, infrared radiation into the infrared detector of abating. Through the two light intensity ratio and correction, measure the concentration of CO in the sample gas
