The Model 909 Radiation Dosimeter Charger is an easy-to-use device that is able to charge (zero out) any self-reading dosimeter. Its spring-loaded contact and mechanical design protects dosimeters from damage by excessive charging force. In addition, it automatically removes residual static charge from the dosimeter’s charging pin each time a dosimeter is re-zeroed, thus eliminating a significant source of error-causing fiber movement. The charger is constructed of rugged ABS plastic, and incorporates a reading light to enable direct reading of a dosimeter without the need to remove it or disconnect it. User directions are printed on the face of the instrument. A tethered dust cap for the charging pedestal is included.  See dosimeter Models AT-138 and AT-725.
