The precautions for maintenance of the infrared gas analyzer are as follows: When using a multimeter with an ohmic stop, remember not to carry out live measurement. When using a logic pen or oscilloscope to detect signals, pay attention not to make the probe contact the two measurement pins at the same time, because the […]

System Structure and Hardware Design of Infrared Gas Analyzer
1 System structure of infrared analyzer The system structure block diagram of the infrared analyzer is shown in Figure 1. TMS320F2812DSP sends a certain frequency modulation signal to control the infrared light source. The infrared light emitted by the infrared light source passes through the gas chamber filled with the gas to be measured and […]
Structure and Working Principle of Infrared Gas Analyzer
Infrared gas analyzer is made using the principle that liquid chemical reagents of different formulations selectively directly absorb certain components of gas. Specifically, it is the nature of certain chemical reagents (absorbents) that chemically react with CO2, O2, and co in the exhaust gas, so that a certain amount of exhaust gas is contacted with […]
Precautions in the Use of Oxygen Analyzer
When performing oxygen content analysis, especially trace oxygen analysis, the oxygen content in the air is as high as 21% O2, so if it is handled improperly, it is easy to cause contamination and interference to the sample, and the analysis result data is incorrect. The main reason is improper operation of the oxygen analyzer. […]
Learn How the Portable Infrared Gas Analyzer Works
Portable infrared gas analyzer belongs to non-spectral infrared gas analyzer. Its working principle is based on the selective absorption of infrared rays by certain gases. A new intelligent industrial on-line analyzer using a single light source, a single-tube semi-gas chamber, an advanced series thin-film micro-tone detector, and a new type of microcomputer single-chip microcomputer technology. […]
Introduction of Infrared Gas Analyzer
Gas industry terminology. The vibration and rotation spectra of most gas molecules are in the infrared band. When the frequency of the incident infrared radiation is the same as the characteristic frequency of the vibrational rotation of the molecules, the infrared radiation will be absorbed by the gas molecules, causing the attenuation of the radiation […]
