The Neutronics Model Pure N2 Portable Trace Oxygen Analyzer is a portable analyzer designed to accurately measure oxygen in the range of 0.1 ppm to 100%. Featuring the Neutronics rapid response zirconium oxide sensor with its extremely fast response and high accuracy, the Model Pure N2 can be exposed to air and within seconds read ppm oxygen in a variety of background gases, including nitrogen, argon, and helium.
The Model Pure N2 is a completely self-contained instrument that is unaffected by position or motion. The unit includes a built-in high purity sample pump to extract the gas from a process sampling point. Sample gas is directed through the internal tubing to a pressure release bypass valve that controls the system back pressure and a slipstream flow allowing for a faster response time. A fixed orifice is used to reduce the pressure and flow of the sample gas as it flows to the sensor.
