The HDER-G01 is the model name assigned to this military-grade Geiger counter set. The equipment was originally designed for the United States Navy as the AN/PDR-27S Radiac set. According to the Homeland Defense Equipment Reuse Program, the retail "acquisition" value of each of these radiation detection sets is approximately $1,400. We have a very limited number of these available, and when they’re gone, they’re gone.

The Homeland Defense Equipment Reuse Program was established by the U.S. Department of Energy (DOE) in cooperation with the United States Department of Justice (DOJ), and became a nationwide program in 2002. The program is coordinated by the DOE in Oak Ridge, Tennessee. The purpose of the HDER program is to refurbish, package, and distribute surplus DOE equipment to appropriate agencies nationwide, with the intention of providing equipment potentially valuable in mitigating terrorist, chemical, biological, radiological, and nuclear threats.

This same equipment is currently in use by law enforcement agencies nationwide.

• ***This meter set is in good working order!
• Built like a tank, this Geiger radiac set has been professionally refurbished and repackaged. Even though it’s heavy-duty equipment, it operates on only two standard D-cells (included). This unusually lightweight kit (weighing only 6.6 pounds), includes a rubber-gasketed case and rubber-gasketed Geiger survey meter. Both are designed to be water-resistant. The construction of the meter body and equipment case appears to be aluminum or some other non-rusting metal compound.
• By virtue of the dual-Geiger tube probe design, the meter can detect both Gamma and Beta radiation. It is capable of measuring up to 500mR/hr of gamma radiation and can detect the presence and relative intensity of beta radiation. The meter scale automatically changes to reflect the sensitivity selected by the rotating range switch. Four sensitivity ranges are provided at 0-0.5, 0-5, 0-50, and 0-500 mR/hr. There is also an "off" and battery test position on the range switch. A rubber-covered momentary pushbutton switch illuminates the meter for use in total darkness.
• The meter includes a BNC connector for headphones, if desired. The connector has been tested for proper function, but no headphones were included with any of these HDER-G01 sets, and none is included here. Radiation detection will be reported through the sensitive meter movement mounted to the detector.

*The illustrations are stock photographs which show a typical meter set. There may be very slight variations, such as color of protective cap on the spare G-M tube. Some meters have scuffs and scratches, and some cases may have superficial scuffs and scratches and/or patches of paint removed by the refurbishment process (original AN/PDR-27 Navy labels were removed), but nothing which affects operation.
