ELEMENTRAC ONH-p

Equipment Description

The ELEMENTRAC ONH-p is an oxygen, nitrogen and hydrogen analyzer in inorganic samples based on thermal extraction with carrier gas and equipped with a pulse furnace that reaches temperatures above 3000 ° C.

It is characterized by its precision and speed, in addition to offering a wide variety of application possibilities for the analysis of metals, ceramics and inorganic samples.

It can be equipped with up to 2 independent infrared cells that allow you to determine the oxygen content in both high and low concentrations. Nitrogen and hydrogen concentrations are measured in it by a robust and highly sensitive thermal conductivity cell.
