Product Summary

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.
