Large display with luminescent backlight, which provides simultaneous display of measurement units, measurement errors, threshold level, real-time; and an analog indicator of instantaneous radiation intensity
-
Ability to perform measurements with a preset error
-
Prompt evaluation of gamma background within 10 seconds
-
Automatic subtraction of gamma radiation component when measuring beta radiation parameters
-
Automatic subtraction of gamma and beta radiation components when measuring alpha radiation parameters

Programming of threshold levels of the alarm system activation for each parameter of measured radiation
-
Automatic setting of measurement intervals and ranges
-
Audio signaling of each registered gamma quantum, alpha or beta particle with the possibility of its deactivation
-
Two-tone audio alarm of exceeded programmed threshold levels
-
Recording in nonvolatile memory up to 1 000 measurement results
-
Viewing the measurement results previously recorded in non-volatile memory on the indicator, as well as transferring the information to a personal computer via Bluetooth
-
Four-level indication of the battery discharge
-
New software has been developed to work with the device
-
Software is used for:
– readout of measurement results from the dosimeter memory into the PC as a dosimeter measurement protocol
– viewing measurement results on the PC monitor, preparing and printout of reports, saving measurement results to a file without changes or as a report for further use
