ONH-2000 Oxygen Nitrogen Hydrogen Determinator

The ONH-2000 is designed for the rapid and accurate determination of oxygen, nitrogen and hydrogen in copper, steel, cast iron, alloys, zirconium, titanium, molybdenum, nickel, ceramics and other inorganic materials.

The OHN-2000 can be supplied with two independent infrared cells to provide optimum precision for the analysis of high and low levels of oxygen. Nitrogen and hydrogen are detected with a dual range thermal conductivity cell. The changeover from the low to high levels is done automatically during the analysis and does not require any pre-setting by the operator.

The ONH-2000 can alternatively operate as a simultaneous oxygen & nitrogen Analyser or as a hydrogen analyzer. The changing from O/N to H mode and reverse is easily done from a switch. The carrier gas cylinders are selected by solenoid valves controlled by the change over switch. Schutze Reagent is used as a CO to CO2 converter when analysing for hydrogen, while for O/N operation heated Rare Earth Copper Oxide (600°c) is used as the catalyst.

The ON-900 features a microcontroller and solid state infrared detectors with auto zero and auto range control.
