The unit operates in LN (low noise) mode for smooth readings and the measurements are made independent of sample pressure, gas temperature and other gases including CO2 and H2O. Gases other than oxygen will, in most cases not affect the measurement except for their dilution effect on the gas mixture. The Model O2L features an easy to use and feature bright LED displays, touch ...

    O2iM Oxygen Deficiency Monitor

    O2iM Oxygen Deficiency Monitor


    The Oxigraf O2iM may be the oxygen safety monitor you need to avoid an oxygen depletion hazard.

    You want a rock-solid and immediate oxygen alarm for concentration less than 19.5% in the event of a cryogenic spill leading to rapid displacement of breathing air.

    You also want an end to frequent recalibration or replacement of oxygen sensors, high maintenance of sampling systems, false alarms, and failure to alarm.

    O2N2 Oxygen Analyzer


    An On-Board Inert Gas Generation (OBIGG) system is now mandatory for many civilian and military aircraft to prevent the buildup of explosive conditions in fuel tanks by generating Nitrogen Enriched Air (NEA) to lower the oxygen content in the fuel tank headspace or ullage. Oxigraf provides a complete system for validating the performance of your OBIGG system.

    The Oxigraf O2N2 oxygen analyzer characterizes the performance of an OBIGG system over an entire flight profile from takeoff, climb, cruise, and descent by measuring the oxygen concentration at multiple sites in the fuel tanks every 16 seconds.

    The O2N2 analyzer is a specialized instrument evolved from Oxigraf oxygen analyzers commonly used for medical, scientific, and ...

    O2Mix O2 and CO2 Gas Mixer


    Overlay and Sparge Gas Controller for Bioreactors.

    The Model O2MIX gas mixer measures the oxygen and CO2 concentration in a gas sample inside instrument and uses this as feedback to control three (3) proportional valves to blend gasses from the three (3) inputs to a single output. The product uses feedback from actual gas measurements as a control point and different mixture and blends of gasses can be used to feed three (3) inputs for mixing. In normal operation the O2MIX is designed to accept Oxygen, Nitrogen (or Compressed “Air”) and CO2 as inputs, and a single blended output of a programmed mixture is produced by the unit to feed a Bioreactor.

    • Accurately mixes O2 and/or CO2 with air or nitrogen by ...
