Harshaw TLD 5500 Thermoluminescence Dosimetry system

The Thermo Scientiffc™ Harshaw™ 5500 TLD Reader is an automated, high capacity hot-gas TLD reader designed for processing un-mounted dosimeters. Ideal for higher volume applications in medical physics, health physics, material research, and industrial applications, the Harshaw 5500 can automatically process up to 50 dosimeters per reading session, to efffciently deliver accurate results with reduced manpower. Compact, attractive reader has a linear, programmable heating system and a cooled photomultiplier tube with associated electronics to measure the TL light output. The WinREMS Software, which runs on a separate computer, provides the user interface, the reader control and the applications software.
