OverviewDissolved Hydrogen MeasurementSpecificationsResources

Monitor for continuous measurement of dissolved hydrogen in water steam cycles.

  • Monitor AMI Hydrogen QED having Complete system mounted on stainless steel panel:
  • Transmitter AMI Hydrogen in a rugged aluminum en-closure (IP 66).
  • Flow cell QV-Flow PMMA OTG made of acrylic glass with needle valve and digital sample flow meter on mounting angle made of stainless steel.
  • Swansensor Hydrogen with platinum anode and silver cathode and integrated NT5k temperature sensor.
  • Faraday electrode for the automatic or manual verifi-cation by electrochemically generated hydrogen con-centration in the ppb range.
  • Factory tested, ready for installation and operation.
  • Measuring range: 0.01 ppb to 800 ppb H2 (at 25°C, 1013hPa) or 0 – 50% saturation
  • Simultaneous measurement of dissolved hydrogen, sample temperature and sample flow.
  • Big backlit LC display for the reading of measuring val-ue, sample temperature, sample flow and operating status.
Swansensor Hydrogen with platinum anode and silver cathode and with inte-grated NT5k temperature sensor.
