Automated TLD reader for dosimetry services and high-volume labs, processing up to 1400 TLD cards per run at 140 cards per hour.
The Harshaw 8800 Plus is Thermo Fisher’s highest-capacity TLD reader, designed for dosimetry services and independent dosimetry labs. Each dosimeter is calibrated individually, and an integrated barcode reader time-stamps every card to maintain an unbroken chain of custody. The reader is available in three versions: standard, with the EXT-RAD option, and with the DXT-RAD option for extremity dosimeters.
The reader is controlled from WinREMS software on a separate computer and can be networked with other Harshaw manual and automatic readers. Cards and materials are covered under Harshaw TLD Readers, Cards and Materials.
