Dosimeter Charger, Model 909

"The Dosimeter Corp. Model 909 Dosimeter Charger is a self-contained, battery operated instrument capable of charging any self-reading pencil dosimeter. Assures grounding of the dosimeter charging pin and removal of the residual charge, also known as ""kick."" The zeroing knob has a push rod in its center that permits reading of the dosimeter without removing it from the charging contact pedestal. The dosimeter circuit is powered by a 1.5 volt battery and is capable of producing a variable voltage up to 220 volts at the center electrode of the charging contact. The push rod is actually a two-position switch that first shuts off the high voltage to the charging contact and then illuminates it for reading dosimeters. Instructions included. This item is sold as is. We do not warrant its functionality."
