TH2004Infrared Absorption CO Analyzer belongs to non-scattered infrared analyzer, whose optical system is composed of power, air chamber, detector. The power system is made up of

prepositive magnifier, main magnifier, constant-current output circuit, temperature control device, power supply unit.

Main features:

1. easy operation

2. automatic range conversion function

3. automatic compensation function of temperature and pressure

4. adopting Kalman Filtering method, making the ratio of response time and signal-to-noise achieve the best optimization.

5. simple structure, easy maintenance.

6. diagnosing instrument internal working parameters remotely

7. RS-232/RS-485 digital transmission method and simulation signal transmission function

Operating principle:

TH-2004Infrared Absorption CO Analyzer adopts the non-infrared absorption method. The basic operation principle : CO has the hydroscopicity to infrared radiation of a particular wavelength(4.6μm). Its concentration has the nonlinear abate relationship with infrared emission.
