The Device Features:

Multilingual Interface: English, Russian, German, French, and Italian with possibility to extend further.
Constant Environmental Radiation Monitoring, all data are automatically stored for the period from one hour to two years, including storage in energy-saving mode (data can be viewed at any time in the form of a chart or a table on device or PC display).
Generate and view reports on the device.
Direct data transfer to PC via micro-USB cable (all data can be printed out).
Ambient temperature is measured automatically and displayed on the screen.
Data and time in the menu can be adjusted individually.
Hazards are revealed with the help of a chart on the screen (which simplifies the search).
The average background radiation is defined automatically with possibility to select readings for one month or one day, and is visualized.
Adjustable alarm value of audible/graphical alarm (also possible in energy-saving mode).
Large, 2.0-inch color LED-display with 240 x 320 pixels resolution.
