The Model O2T oxygen analyzer for medical oxygen trans-filling and verification is designed for measuring 5-100% oxygen in nitrogen. The unit features an easy to use and feature bright LED displays, touch panel controls, easy calibration, and a CPC front panel fittings. The Model O2T has a built-in sampling pump with flow from 0-250ml/minute.

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
