Triple range thermal conductivity hydrogen purity analyzer

Sent Email : [email protected]

ZA-2001 triple range thermal conductivity hydrogen purity analyzer (analyzer + sampling system) adopts sensors based on reliable and stable thermal conductivity principle developed by Honeywell (USA) to provide high sensitivity and accurate analysis on two-phase gases. It is designed for monitoring the hydrogen purity in the generator and gas purity during the gas replacement process in generators. It is widely used in power plant.


  • Appointed auxiliary products in generator plant.
  • Meet the need of gas detection during generators operation and gas replacement .
  • A wide range of temperature compensation technology.
  • Accurate sampling system.
  • Unique automatic blowdown technology and safe bypass function.
  • Explosion-proof sensing unit, reliable operation performance, quick response speed.
  • Cabinet of installed analyzers and sampling system, convenient to calibration on-site.
