Panasonic UD-7900 User Manual

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 (pulse­counting) 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.
