Trace O2  |  0 to 1,000 PPM Range

Model 7100P

Portable/ Benchtop Series
Internal ZR400 Sensor

The Neutronics Model 7100P 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 1,000 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 7100P includes a pump for extractive sampling. The flowmeter on the front panel provides accurate and easy-to-read visual flow readings.
