Energy-compensating filter, which allows to obtain a reliable energy dependence of the radiometer readings when measuring photon ionizing radiation in the energy range from 12 KeV to 3 MeV
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
