DA-3000A Semi-automatic TLD Reader is a highly reliable and cost-effective thermoluminescent reader that can effectively measure the radiation dose absorbed by the thermoluminescent material contained in the dose box.
The reader is integrated with an automatic sample introduction/ejection system, which can automatically read up to 120 dosage elements in one load, supporting multi-batch continuous measurement.
The system software integrates a result database, so operators can easily manage measurement data in various formats and generate measurement reports in specific formats.
