Trace to Percent O2  |  0.1 PPM to 100% Range

Model Pure N2

Portable/ Benchtop Series
Internal ZR100 Sensor

The Neutronics Pure N2 is a portable analyzer designed to accurately measure oxygen in the range of 100% to 0.1 ppm.  Featuring the Neutronics rapid-response zirconia 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 unit includes a high purity sample pump for extraction of the gas from the sampling point.  A pressure release bypass valve controls the system back pressure and a fixed orifice reduces the pressure and flow of the sample gas to the sensor.
