(Fixed PPM) Model 7100 – 0 – 2,000 Parts Per Million (PPM) Range Oxygen Analyzer
The Ntron Model 7100 provides an affordable and versatile Oxygen Analyzer solution that’s ideal for high-purity gas manufacturing, high quality welding applications, semiconductor manufacturing applications and any other application that requires precise measurement of oxygen. The unit provides high-purity gas measurement in a range of 0 – 2,000 ppm.
A small footprint and compact size makes the Ntron 7100 easy to install. The unit’s expected operational life is five to ten years. The low-maintenance, long-life Zirconia sensor has virtually unlimited shelf life and will not dry out or freeze.
