Purpose and application scope

　This analyzer is used for continuous analysis of the content of a gas such as CO, CO2, SO2, CH4, NH3, etc. in multiple gas mixtures. The product has a wide range of applications:

1. Used for environmental monitoring of atmospheric and pollution source emissions;

2. Used for process control in industries such as petroleum, chemical, and power plants;

3. Used in fields such as agriculture, healthcare, and scientific research;

4. Determination of gas content in various combustion tests in the laboratory;

5. Used for air monitoring in public places;

working principle

　　The DFX-IR-C infrared gas analyzer belongs to the non dispersive infrared gas analyzer, and its working principle is based on the selective absorption of infrared radiation by certain gases. The instrument adopts a single light source, a single tube separated half chamber, and a series connected thin film micro sound detector, with high process, analysis accuracy, and good stability. Adopting * digital processing technology and a brand new LCD display screen.
