Eltra Hydrogen Analyzer H-500

Eltra Hydrogen Analyzer H-500

In the early 1980’s the development of its first Carbon and Sulfur Analyzer led to the creation of ELTRA. The objective to offer high quality products at affordable prices still remains the foundation of ELTRA’s policy today.

Hundreds of satisfied customers worldwide are proof of the quality and reliability of Eltra analyzers.  With the creation of new levels of performance-to-price-ratios ELTRA’s world market share has rapidly increased.

The introduction of oxygen, nitrogen and hydrogen analyzers allowed ELTRA to successfully enter new markets on a global level. ELTRA equipment is the standard for elemental analysis in industries such as steel, automotive, mining and aerospace.


Determination of hydrogen using the heat extraction method is a special requirement for the characterization of steel, steel alloys, copper and other metals. ELTRA’s H-500 is designed for the rapid and accurate determination of hydrogen in these materials.

The H-500 analyzer uses the heat extraction technique and is equipped with a resistance furnace with quartz tube. The temperature can be set up to 1000 °C in steps of 1 °C. The usual working range of the H-500 is about 900° to 1000° C. ELTRA’s H-500 can be customized to the requirements of the user. The analyzer carries up to two different sensitivities of the detectors to allow highest precision for a variety of applications.


  • Hydrogen determination with heat extraction technique for determination of residual hydrogen
  • High-capacity thermal conductivity cell
  • Easy calibration with standards or gas dosing
  • Precise measurements even for low concentrations
  • For samples of up to 10 g and 0.8 x 6 cm size
  • Powerful software (multilingual, customized display, export of results)
  • Low maintenance
  • Robust design allows usage in production control and laboratory
