DA-3000A Semi-automatic TLD Reader
Product introduction
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.
Features:
Ø Automatic sample injection, ejection, measurement and data processing, one load can
automatically and continuously measure 120 dosage chips and can read 100 chips per hour
Ø Accurate measurement, using wide range, high resolution, high
stability, intelligent amplifier, and extended range
Ø Safe, reliable, and stable in operation. The core components, CU,
and interface chips are all domestically produced devices, with
strong substitutability and good supply guarantee capabilities.
Ø It is simple to operate and has a good human-machine interface for
convenient and quick operation. It has built-in diagnostic
function, running process display and voice prompt function.
Ø Rich interfaces, with standard S232/USB/RJ45 network interface
