Designed to make the task of trace oxygen analysis easier, faster and more precise than ever before

    • Insta recovery advanced micro fuel cell sensor
    • Display gas concentration, units
    • Extensive self-diagnostic testing at start-up and on demand with continuous powersupply monitoring
    • Auto ranging capabilities
    • One high and one low alarm set point with corresponding relay contacts
    • Sensor failure alarm
    • Extended-life, maintenance-free sensor.one year warranty and an expected life of two years
    • Graphic display screen, continuously prompting and informing the operator
    • High resolution, accurate readings of oxygen content from low ppm levels through 25%.


Custom Engineering is HNL’s main strength. HNL maintains in-house capability to both design and manufacture a wide variety of sample systems tailored to meet out customers’ process requirements. We design sample-conditioning systems for our complete line of process analyzers .

The trace oxygen analyser can be ordered as a standard unit or as part of a larger cost effective integerated analytical system. The analyser can also be supplied designed as a “split architecture” instrument, meaning that a general purpose, panel mounted control unit for non-hazardous areas controls a remote analysis unit(Transmitter) that can operate in hazardous areas.
