The Neutronics 7100P Portable Trace Oxygen Analyzer is a portable analyzer designed for trace oxygen gas measurement in pure gases such as nitrogen, argon, and helium. This analyzer features a rapid-response mini-zirconia sensor with a measurement range of 0 to 1000 ppm oxygen. Extremely fast response, high accuracy, and simple calibration make this portable analyzer a low-maintenance solution that delivers reliable performance in a rugged light-weight steel enclosure.

The ZR-400 sensor is a non-depleting solid state device based on a zirconia electrolyte cell. With an integral heater and two electrodes, it is mounted directly onto a printed circuit board that supplies bias and heater voltages to the sensor element. A small capillary on the sensor surface controls diffusion of oxygen into the sensor. At operating temperature, oxygen is electrochemically reduced, causing current flow through the solid electrolyte. Oxygen concentration in the sample gas is determined by measuring the current flowing through the electrodes.
