Oxygen / Nitrogen / Hydrogen Analyzer ELEMENTRAC ONH-p 2

Oxygen / Nitrogen / Hydrogen Analyzer ELEMENTRAC ONH-p 2

Eltra | Chemical Identification

The ELEMENTRAC ONH-p determines oxygen, nitrogen, and hydrogen in inorganic samplesby inert gas fusion in an impulse furnace with temperatures in excess of 3.000 °C.

The ELEMENTRAC ONH-p guarantees precise and fast sample analysis. The analyzer covers a wide range of applications such as metal, ceramics and other inorganic materials.

The ELEMENTRAC ONH-pcan be supplied with up to two infrared cells with different path lengths, accommodating both high and low level oxygen analyses. Nitrogen and hydrogen concentrations are determined in the ELEMENTRAC ONH-pby a robust and sensitive thermal conductivity cell.
