EZ-MAT: ATM Oxygen / Hydrogen Analyzer ELEMENTRAC OH-p


The ELEMENTRAC OH-p determines oxygen and hydrogen in inorganic samples by inert gas fusion in an impulse furnace with temperatures in excess of 3,000 °C.

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

Application Examples

alloys, cast iron, ceramics, copper, refractory metals, steel, ...
