Oxigraf, Inc. - O2TR and O2T Oxygen Analyzers

The Model O2T and O2TR are oxygen analyzers for medical oxygen trans-filling and verification and designed for measuring 5-100% oxygen in nitrogen. These units are easy to use and feature bright LED displays, touch panel controls, easy calibration, a sample pump or regulator for flow control depending on model, and CPC front panel fittings. The Model O2T has a built-in sampling pump with flow from 0-250ml/minute. The Model O2TR has a built in regulator for flow control and features a simplified two (2) point calibration control on the front panel.

Step-Up from other measurement technologies:

NO errors due to vibration and movement
NO errors due to temperature changes
NO errors due to changes in barometric pressure
Fast response in seconds to conserve gas
