The New Generation: ELEMENTRAC® ONH

ELTRA presents the latest generation of ONH analyzers for the determination of oxygen, nitrogen and hydrogen in inorganic materials with a fresh new design and advanced features.

Highest precision with even better reproducibility of the measurement results combined with a considerably reduced consumption of carrier gas are the main features of the ELEMENTRAC® ONH series. The core of the new analyzer is the powerful impulse furnace with ELTRA’s optimized sample drop mechanism which allows for a wide range of sample materials and sizes: from granules to whole pieces of materials such as steel, copper, titanium or silicon.

The new analyzer generation is equipped with a precisely tuned IR measuring system (furnace, catalyst, IR detector) for oxygen determination. Nitrogen and hydrogen concentrations are measured by highly sensitive thermal conductivity cells which provide accurate results even for very low measuring ranges. For the first time it is now possible to use consumer-friendly argon as carrier gas.

The comprehensive software is easy-to-use and offers a variety of diagnosis and analysis     tools     which simplify routine tasks in the laboratory.


·          High precision and reduced gas consumption thanks to newly developed furnace

·          Highly sensitive determination of hydrogen and nitrogen by thermal conductivityanalyses

·          Precise oxygen measurement from ppm level to percentagerange

·          Optional use of argon as carriergas

ELTRA is one of the world's leading manufacturers of elemental analyzers for rapid and accurate analysis at affordable prices. Starting with combustion analyzers for carbon and sulfur determination in the early 1980’s ELTRA has extended its product range over the years with analyzers for oxygen, nitrogen and hydrogen as well as thermogravimetric analyzers. Thousands of satisfied customers worldwide are proof of the quality and reliability of Eltra instruments.
