(The program is a programming model that runs on a PC (OS Windows), and behaves almost identically to the real device)

  • ease of operation thanks to pocket size, optimal the algorithm of definition of the radiation background, availability of easily readable large alphanumeric LCD display with backlight and ease of control;
  • voice dubbing and voice evaluation of the results of measurements of dose rate of gamma – radiation;
  • audible and visual alarm radiation intensity;
  • simultaneous display with backlight name of the mode of operation, results and units of measurement, current statistical error and analogue scale, the maximum value of which is determined by the established threshold alarm measured value;
  • fast change of instrument readings when statistically significant change of the intensity of the radiation;
  • tone sound signaling when exceeding a user-defined threshold dose, dose or beta – particles flux density;
  • storage in non-volatile memory of up to 2000 of the measurement results with the date and time of holding;
  • possibility of data exchange with a PC (via USB port).

Area of application

    • civil defense and emergency situations
    • service of radiation monitoring at nuclear power plants, industrial enterprises and medical radiological institutions

customs services

  • the search for sources ionizing radiation
  • detection of radioactive contamination of banknotes and their packages
