5500 TLD Reader

5500 and pc_0.jpgThe Harshaw 5500 TLD Reader provides cost-effective measurements of the radiation dose absorbed by individual TLD elements. The instrument includes an automatic sample changer and carrier disk for automatic processing of up to 50 TLD dosimeter elements in a single loading.

5500 Carrier diskThe 5500 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

The 5500 can read chips rods or microcubes using a variety of carrier disks designed to handle the different types of detector. Carrier disks are chosen on purchase to suit the detector types use
