Automated table-top hot-gas TLD reader for un-mounted dosimeters, processing up to 50 dosimeters per run without operator intervention.
The Harshaw 5500 is an automated, high-capacity reader for un-mounted TLD elements, suited to higher-volume applications in health physics, materials research and industrial dosimetry such as radiation hardening and environmental studies. It is available in two versions, Micro pick and Macro pick, to accommodate different sizes and forms of TLD material. The reader is controlled from WinREMS software on a separate computer.
TLD materials and accessories are covered under Harshaw TLD Readers, Cards and Materials.
