The ON-900 is designed for the rapid and accurate determination of oxygen and nitrogen in steel, cast iron, alloys, copper, zirconium, titanium, molybdenum, nickel, ceramics and other inorganic materials. The ON-900 can be supplied with two independent infrared cells to provide optimum precision for the analysis of high and low levels of oxygen. Nitrogen is detected with a dual range thermal conductivity cell. The change over from the low to the high ranges is done automatically during the analysis and does not require any pre-setting by the operator. The ON-900 features a microcontroller and solid state infrared detectors with auto zero and auto range control. The water cooled high power electrode impulse furnace uses a graphite crucible to heat the sample up to a temperature of 3000X C.
On request the ON-900 measuring ranges can be optimized in the factory to suit your requirements, without additional charges. The sensitivity of the detectors can be designed to provide maximum accuracy in ranges from low ppm up to high percentage concentrations.
