The UD-7900 reader is the latest reader type offered today by Panasonic.  Our readers came from operating dosimetry labs that closed.  They are all unconditionally warranteed.  We recommend you purchase laboratory management software to go with these readers.  The cost varies as there are a few versions out there that range from $20,000 and up.

The UD-7900 Reader automatically reads all “UD-800 Series” TL Badges with high reproducibility and precision. Using the non-contact optical heating method, the reader can measure a large number of TL badges at high speed with reliability.  Both the photon-counting method (pulse-counting) for small signals and the current integration method for large signals are employed to precisely detect the thermoluminescence throughout a wide range from low to high doses.

The reader is equipped with self-checking functions for the optical path; sensitivity of PM tube, heating stabilty etc. It also performs

automatic functions such as annealing of the TL badges for repeat use, optical reading of the ID code, and sensitivity adjustment correction by the built-in reference light source.Pre-heating, annealing, and ID code optical reading are also incorporated
