• Small size portable professional device intended for measuring
  • Measurement of gamma and X-ray radiation ambient dose equivalent rate.
  • Measurement of gamma and X-ray radiation ambient dose equivalent.
  • Measurement of surface beta-particles flux density.


  • Independent measuring channel: gamma-radiation dose power and flux density of beta-radiation
  • Continuous measurement with constant specification of the result
  • Assessment of the radiological situation by the sound signals (clicks), frequency of which is proportional to the dose power (flux density)
  • The resultof measurement with any necessary statistical error
  • Automatic restart of the device when changing the type of measured radiation while measuring.
  • Compensation of the counting rate due to the presence of gamma radiation while measuring flux density of betaradiation
  • Indication of statistical error while measuring
  • Indication of unit of measurement
  • Indication of the level of battery charge
  • Backlight display
  • Pocket size


  • Sensitivity which is sufficient for correct measurements on the natural background, combined with a high upperlimit of dose rate measurement
  • Using the device as a personal dosimeter for automated systems for collecting dosimetric data due to its abilityto transmit time-referenced data about the accumulated dose
  • Keeping an internal archive of values of accumulated dose int he non-volatile memory-not less than 2000 records
    Possibility to set from 1 to 3 values of alarm level limits and there is a sound in case of exceeding these limits
  • Control and alternation of parameters is performed using keyboard or PC with specialized software
