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.
