working principle

The instrument uses the principle of thermal conductivity detection, and the core detection component is a constant temperature thermal conductivity sensor with temperature compensation function. The thermal conductivity sensor consists of two chambers, each with an identical thermal conductivity meter. One of the chambers is sealed and filled with reference gas, while the other chamber receives sample gas. The controller converts the difference in thermal conductivity between the reference gas and the sample gas into the current concentration value of the detection sample gas. As long as the thermal conductivity coefficients of the two components in the mixture are different, the instrument can detect this component in the mixture. Depending on the gas being detected, the range can be from 0.01% to 100%. Utilizing advanced linearization processing techniques to provide high-precision detection. The detectable gases include hydrogen and hydrogen₂Carbon monoxide CO, carbon dioxide CO₂, argon gas Ar, helium gas He, hydrocarbon C_XH_YAmmonia NH₃Sulfur hexafluoride SF₆Fluorine, etc. If used to detect hydrogen He_{，The detectable range is any range between 0-1% and 0-100%.}

Instrument structure

We can provide different types of packaged thermal conductivity gas analyzers according to user operating conditions:

1. Portable or desktop: If portable, the instrument is enclosed in a sturdy, weather resistant casing. Use rechargeable batteries for power supply; The inlet and outlet of desktop instruments are designed in front of the instrument, making it easier for users to operate. In addition, targeted gas path design is provided for different pressures, gas intake volumes, and response requirements.

2. Online wall mounted, rack mounted, or disk mounted: There are both safe area use types and partially or fully explosion-proof types suitable for use in hazardous environments.
