The software integrates a results database, allowing operators to easily manage measurement data in various formats and generate measurement reports in specific formats.

The equipment has irradiation device and can be equipped with various nuclide gamma radiation sources for calibration or calibrating of the instrument, with automatic TLD chips selection function.

A single load can automatically and continuously read 200 dosimeters, each dosimeter contains 4 dose elements.

Card-readable whole body dosimeters, ring and wrist dosimeter tablets

The four-element card dosimeter is heated and read simultaneously, and can read at least 200 dose elements per hour.
