Oxygen in Hydrogen measurement

Mechatest design for electrolyser solution an Oxygen (O2) gas in green Hydrogen (H2) gas measurement solution (also known as O2 in H2 wet gas sensor) that allows for analysis of the wet gas Oxygen (O2) stream in Hydrogen (H2) composition.

The output of the electrolyser is green Hydrogen (H2) and Oxygen (O2) as a wet gas composition. To take in a wet gas a Oxygen (O2) sample is not easy, most sensors for this typical measurement in this acceptable price range are mostly not suitable for wet gasses.

Based on our experience we designed solution with fallback probe, membrane filtration with liquid blocker, and prevent the Oxygen (O2) sensor from harmfull wet gas and extend lifetime much more.


Oxygen (O2) is an explosive and dangerous gas, humans and the environment are subjected to high safety risks, the Mechatest Oxygen (O2) measurement solution is suitable for explosion dangerous areas.

Electrolyser Oxygen (O2) Gas Measurement

The big advantage of the measurement of wet gas Oxygen (O2) sample in an electrolyser system is to prevent the Oxygen (O2) sensor and assure a long lifetime and quality proof measurement.
We have improved our sampling systems for gas by:

  • Creating closed loop systems emission free which provide a safe, controlled environment
  • Suitable for high pressure process application
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent Oxygen (O2) measurement systems, and professional services by our team of specialists.
