The Thermo Scientific™ HARSHAW TLD™ Model 3500 Manual Reader provides manual readout of TL chips, disks, rods and cubes in a broad variety of sizes. This reader is suitable for all kinds of applications that require thermoluminescence dosimetry (TLD) detectors. Due to planchet heating, this versatile model is able to read powders, an essential feature for food testing and analysis.

The HARSHAW TLD Model 3500 Manual Reader includes a sample drawer for a single element TL detector, a linear, programmable heating system, and a cooled photomultiplier tube with associated electronics to measure the TL light output. Planchet heating incorporates a welded thermocouple for best temperature reproducibility. The operational software, Thermo Scientific™ WinREMS™, which runs on a separate computer, provides the user interface, the reader control and the applications software.
