7100氧气分析仪

The Ntron Model 7100 provides an affordable and versatile Oxygen Analyzer solution that’s ideal for high-purity gas manufacturing, high quality welding applications, and semiconductor manufacturing applications. 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.
