    In the beer and beverage industries, the content of dissolved oxygen (O2) is extremely important to both product quality and taste. Excess O2 can compromise the flavour stability and lead to significantly reduced product shelf life.

    Except easy and reliable determination of dissolved O2 (Dissolved Oxygen) the Haffmans Portable Optical O2 Meter o-DGM offers:

    Three measurement modes are available; single sample, continuous O2 measurement and TPO measurement.

    The o-DGM is available in two measuring ranges:

    – low measuring range (LHO) for accurate DO measurement of beverages < 2,000 ppb (e.g. beer and aerated water)

    – Accurate product control
    – Reproducible and operator independent results
    – Cost saving
    – Less labour intensive
