Challenges in H2 measurement in electrolysers
  • Moisture in the process gas destroys devices and falsifies measurements
  • Cross-sensitivity compensation or dehumidification of the gas required
  • Reaction times (t90) should be short and require complex sample preparation
  • Some processes involve corrosive gases
  • High operating pressures and process temperatures require additional sample preparation
Mastered by Archigas H2 gas analysers
  • Sensors are not destroyed by contact with condensate
  • Cross-sensitivity of the humidity is significantly reduced
  • Response times are only up to <30 ms
  • Pressures of up to 200 bar are permissible
  • High corrosion resistance is available
  • Continuous online quality monitoring up to H2 4.0 (99.99%) possible
  • Process temperatures of the gas can be up to 130°C
  • Additional costly sample preparation is not required
