Hydrogen Analysers

Reliable process control for furnaces, metal industry, semiconductor and gas separation.

The analyser continuously measures the concentration of gases such as H2, He, and Ar with high stability.

It is also available in a version for hazardous areas (for countries outside the European Union): ZAFE certified Ex NEPSI.


Because the thermal conductivity is different among gas components, when there is a change in the concentration of the component under measurement, the thermal conductivity of the sample gas will change to affect the temperature of the platinum wire.

The analyser uses the temperature change to determine the gas concentration.
