Dosimeter SFIORA double
Parameters and characteristics .


    Dadiation dosimeter
    SFIORA double

Domestic dosimeter for measurement of the environment and objects radioactivity.



SFIORA double is 2-in-1 device:
  • Home dosimeter for measurement of Gamma, hard Beta and X-ray radiation ("total mode", display like at the right photo).
  • Semi-professional dosimeter with separate measurement of Gamma and hard Beta radiation ("separate mode", display like at the left photo).
    Dosimeter instantly switched from one mode to another.

    It has:
    • Beta and gamma radioactivity-time graphs of 64 last measurements.
    • Display of total accumulated radiation dose
    • Counters calibration mode.
    • Sound and vibro alarm with separate thresholds.
    The result of measuring is corrected by software for the sensors noise and sensitivity.
    The measurement cycle is 1 to 16 seconds depending on the radiation and selected mode. Reliable numbers are after 8 cycles.
    On-off and control is by a single joystick.
    Beta radiation is displaed in cpm/cm2. Other ones in mkSv/h.

    Dosimeters are avaiable with green-grey display like at the left photo and with blue like at the right photo.
