Product description

Online Hydrogen Leak Detector


  • Comprehensive monitoring of the generator’s hydrogen leak condition
  • Real-time monitoring of the air leakage at the generator’s bus bar, oil return pipe, water return pipe, sampling valve, internal cold water tank, etc.
  • It can be directly put into oil and water for detection; it uses unique hydrogen sensitive tube bundle that is of good pressure-bearing ability, water and oil insulation, and is oil-insoluble.
  • Simultaneous monitoring of the generator’s safe working status
  • Real-time monitoring of potential hydrogen accumulation positions;
  • Multi-position simultaneous detection;
  • Local display of monitoring data and transfinite acousto-optic alarm
  • Convenient installation and use
  • 16-channel centralized monitoring;
  • Excellent expandability and direct accessibility;
  • High-performance specific integrated circuit to ensure easy data uploading to DCS system.
