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.

Oxygen, Nitrogen and Hydrogen analysis with one instrument Total and fractional analysis for oxides and nitrides separation Hot extraction analysis of residual hydrogen Easy to replace economic upper electrode insert Hot zone at the crucible’s bottom due to graphite tip Grain and drillings analysis without tin capsules PC controlled High temperature electrode impulse furnace for metals and ceramics analysis Catalogue Flow chart Specifications Standards Compliance: ASTM E-1019, E-1587,E-1409, E-1569, E-1447, E-1937 Application notes Consumables

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 or as a simultaneous oxygen & hydrogen analyzer. The changing from On to OH mode and reverse is easily done from a switch. The carrier gas cylinders are selected by solenoid valves controlled by the same On / OH For ON operation, Schutzes reagent is used as CO to CO² converter, while for ON operation the more economic CuO Is used in a catalyst furnace.
 

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