Overview
Thermal conductivity gas analyzer is an effective method to measure one of two components in a gas mixture (the thermal conductivities differ a lot). Mainly used to measure the content of hydrogen (H2), carbon dioxide (CO2), argon (Ar), etc.
Principle
Thermal conductivity gas analyzer is an effective method to measure one of two components in a gas mixture (the thermal conductivities differ a lot). Mainly used to measure the content of hydrogen (H2), carbon dioxide (CO2), argon (Ar), etc.
When the sample gas enters the thermal conductivity cell, and a thermistor is used above the film to maintain a constant temperature. In this way, a small cavity is formed below and above the membrane, and the measurement gas can diffuse into it. In this way, the heat loss caused by the thermal conductivity of the sample gas is compensated by heating, and the power required to maintain a constant temperature of the membrane is a measurement of the thermal conductivity of the measured gas.
Features
• Optional NDIR/NDUV sensor for compensation
For multicomponent gases (>2 species), this optional module isolates specific molecular spectra to eliminate cross-interference for independent measurement.
• Condensation and dust protection Optional
The sintered stainless steel with µm-sized holes is used to protect the sensor.
The PTFE hydrophobic membrane is used to protect the sensor, allowing gas molecules to pass through while preventing liquid water from penetrating.
