Portable Hydrogen Analyzer - 120HD

  • Battery-operated and fully portable
  • Non-destructive measurement (sample can be reused after analysis)
  • All wetted surfaces made of stainless steel
  • Measurement unaffected by changes in ambient temperature or pressure
  • Factory-calibrated

Add to compare

The 120HD Portable Hydrogen Analyzer is a battery-operated, fully portable device designed to measure hydrogen concentration in a gas sample and digitally report the percent volume of hydrogen in air. It operates using a katharometer principle, comparing heat loss from heating coils in two gas-filled tubes to determine hydrogen concentration. The analyzer is highly sensitive to hydrogen due to its high thermal conductivity and can also respond to other gases with different thermal conductivities. It is factory-calibrated, features stainless steel wetted surfaces, and provides reliable measurements unaffected by ambient temperature or pressure variations.

Use Cases

  • On ships
  • In turbine halls
  • During lead-acid battery charging
