Accurate gas measurements require reliable components. Reliable like all of our components.

• Methane CH4: infrared (2-beam), temperature and pressure compensation
• Carbon dioxide CO2: infrared (2-beam), temperature and pressure compensation
• Hydrogen sulphide H2S : electrochemical
• Hydrogen H2 : electrochemical
• Oxygen O2: electrochemical (optionally, paramagnetic for continuous applications)
• Other gases: methods based on the current developments in technology

Remarks:

In our opinion thermal conductivity is not suitable for the measurement of biogas and therefore we do not use this low-cost method in the biogas environment. As biogas is a gas mixture consisting of several components (methane, carbon dioxide, oxygen, nitrogen, hydrogen sulphide, and hydrogen), selective measuring methods should be used for each gas component. Infrared and paramagnetic sensors have a better long-term stability than electrochemical sensors.
