Equipment Description

The determination of the hydrogen content is carried out in the H-500 by thermal extraction. ELTRA H-500 has been conceived for the rapid and precise determination of hydrogen, especially in materials such as steel, alloys, copper and other metals.

The H-500 is equipped with a resistance furnace with a quartz tube that reaches temperatures of up to 1000 ° C, precisely programmable in steps of 1 ° C. The usual working temperature is 900 to 1000 ° C.

This analyzer can be tailored to customer needs and is ideal for a wide variety of applications. Thanks to its dual channel thermal conductivity cell, it can measure very low concentrations precisely.
