TLD-3500 Automatic TLD Reader

The TLD-3500 Automatic TLD Reader is used for periodic monitoring of personal external radiation dose. The equipment automatically measures the thermoluminescent dose meter worn by personnel, accurately and reliably evaluates personal dose data, and detects and collects data by connecting to computer application software and database to form a complete dose file and report.

Main features

Automatically scan and identify the identity information of the dose meter, automatically open the box, automatically take samples, return samples, automatically measure and process data;
100 to 200 special dose meters can be automatically and continuously measured at one time;
Accurate measurement, using wide range, high resolution, high stability
Intelligent amplifier, amplification range 0.1uSv~10Sv, and can be expanded
Safe and reliable, stable operation, core components, MCU, interface chips are all made of domestic devices, strong substitutability, good supply guarantee;
Simple operation, with a good human-machine interface, convenient and fast operation;
With built-in diagnostic function, running process display and voice prompt function;
Rich interface, with standard RS232/USB/RJ45 network interface
The same series of products have type approval certificates
