The patented, handheld Dosimeter Charger works with a variety of direct-reading dosimeters by simply squeezing the lever of a generator. This radiation dosimeter charger is simple to use and requires no batteries. By pulling a trigger, a dosimeter is easily placed in or removed from the clamping action that holds it snugly in the cradle. A discharge button above the clamp easily discharges any charge beyond zero on the meter of your Pen Dosimeter. All you need is a light source and a few seconds to zero your radiation dosimeters and get them back in the field.
