Thermal conductivity analyzer

GasAn-TCD

The thermal conductivity  analyzer (TCD) GasAN.TCD reliably measures gas components in different compositions. The TCD can analyse with up to 4 remote sensors, also it can measure with a built-in sensor. The version with built-in sensor offers various integrated options, such as filter, pump, flowmeter and needle valve. In case of external cells, these can also be installed with gas conditioning.

The analyzer is suitable for applications in various environments in industry and laboratories. It can be used with highly corrosive gases. The GasAn-TCD offers best measurement accuracy and reproducibility of the readings.

The measuring principle uses a heated resistance wire that is surrounded by the measuring medium. The wire changes the resistance value equivalent to an equilibrium temperature and compares this value with a reference value.

The easy-to-use menu is available in several languages can be operated via the easy-to-read touch display.

Sample gases

The measuring device reliably determines the concentration of various gases using the TCD princple. The determinability depends on the difference in thermal conductivity to the background gases. Gases can be analysed using the following table:
