Oxygen / nitrogen / hydrogen analyzers for inorganic samples
Quickly and accurately measure oxygen, nitrogen, and hydrogen levels in metals and ceramics with a robust analyzer designed for precise elemental analysis, ensuring your materials meet stringent quality standards in demanding applications.

Analyzes Oxygen, Nitrogen, and Hydrogen in Inorganic Materials
The ELEMENTRAC ONH-p 2 from ELTRA GmbH is a robust elemental analyzer designed for measuring oxygen, nitrogen, and hydrogen concentrations in inorganic materials such as metals and ceramics. Its unique closed gas system enhances sensitivity and reduces gas consumption by utilizing NDIR and thermal conductivity detectors. This equipment supports industries like metallurgy and electronics, tackling the challenge of precise elemental analysis. With its powerful 8.5 kW impulse furnace, it accurately analyzes samples up to 2 grams in size, whether they are solid, powder, or granular. This ensures optimal integration into laboratory or high-speed production environments. The ELEMENTRAC ONH-p 2 is compliant with international standards, including ASTM E 1019, and supports operations in steel, ceramics, and electronics sectors, delivering reliable results critical for rigorous quality control. Optional features such as the autoloader and autocleaner enhance operational efficiency for high-throughput demands.
