Polimaster Innovating radiation detection technologies since 1992

Display and Control Unit PM1403


Display and control unit cannot be used independently since it is designed to display information when operates together with the external smart probes, to program its operation modes and to identify radionuclide composition.

The instrument indicates the menu and measurement results, stores the accumulated scintillation spectra in its permanent memory, enables communication with PC as well as receives GPS information and transfers data via USB and Bluetooth interfaces.

Operation Principle

The instrument registers gamma/alpha/beta/neutron radiation (DER measurement, count rate, accumulation of the instrumental scintillation spectra of γ-radiation) by means of the external detectors. The built-in microprocessor of the instrument controls the operation modes of the instrument (depending on the type of the connected detector), the LCD backlighting, the matrix LCD, nonvolatile memory, keypad, GPS and Bluetooth modules and processes information coming from the detector. There is a built-in sound alarm speaker in the instrument.

Operation Modes

  • DER measurement of photon radiation

  • search for photon radiation sources

  • measurement of α -, β - radiation flux density

  • registration, accumulation of the γ- radiation scintillation spectra

  • identification of the γ- radiation sources

  • programming the operation modes of the detectors

  • PC-communication
