Saphydose gamma i - Bertin Instruments

    Saphydose Gamma i isotropic electronic dosimeter dedicated to workers exposed to gamma and Xray radiations

    Saphydose gamma i

    The Saphydose Gamma i is an isotropic electronic dosimeter dedicated to workers exposed to radiations. This instrument provides measurement of the Hp(10), dose equivalent for the whole body.

    Saphydose Gamma i is an operational dosimeter measuring radiation in real time (Hp (10) X and γ dose).

    This dosimeter is designed for people working in a controlled area (Nuclear Power Plant, fuel reprocessing plant, research center, hospital, non-destructive testing service…) or likely to be exposed (army, police, fire brigade…). It is compliant with the IEC 61526 standard for measurement of personal dose equivalents. Reliable and ergonomics, the Saphydose Gamma i is appreciate for its sturdy aluminum housing, its high resistance to electromagnetic fields and its long time battery life. It can be used individually or as part of our dosimetry management system.

    • Saphydose Gamma i has a high immunity against electromagnetic interference, as well as a robust schockproof aluminium box

    Low maintenance costs

    • Saphydose Gamma i has a very long battery autonomy: more than 4 years with 2 AA batteries


    • Saphydose Gamma i can be used alone, or integrated in an operational wireless dosimetry system

    Saphydose Gamma i measures X and gamma rays with a reliable dual silicon diode, having a measurement range of dose equivalent from 1 µSv to 9 999.9 mSv. This technology allows an improved stability in comparison with standard GM dosimeters.

    It has a very visible 5 scrolling alphanumeric characters LED Display.
    It has a robust aluminium housing, tested at 10 shocks per side onto steel and 10 cm height of drop, so it can be used in rough conditions.

    It has also a very high immunity against electronic interference, with a 30A/m at 50Hz magentic fiels immunity. It works with one two AA batteries, for more flexibility and autonomy. It is pocket -size and very light (145 g).
