DA-3800 Automatic TLD Reader
Product introduction
DA-3800 is a high-quality, highly reliable and cost-effective
thermoluminescence TLD reader. The reader can automatically measure the built-in dose
card. The reader's integrated automatic sample injection and withdrawal system can automatically
read 200 card-type dosimeters in a single load.
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.
