Digital Radiological Test Equipment PDR-7000
The digital Radiological Test Equipment PDR-7000 is a modern, professional Geiger counter with extensive features. Manufactured by FAG Kugelfischer in Germany to very high military standards.

The counter is auto-ranging with a built-in LCD display that shows the results both digitally and analogue. A power on self test routine makes sure the unit is functioning correctly. The Geiger Counter is so sensitive that it can measure very low normal background radiation. For example, the normal background radiation in London is between 0,07 ?Gy/h and 0,09 ?Gy/h. The unit can take readings externally with a 15 meter probe extension cable and the Gamma Probe DT 7002 as well as the Beta-Gamma Probe DT 7003 and a special probe DT 7004 for testing radiation in liquids.

Operation is by 2 standard 1.5 Volt D size batteries Not Supplied or by a external mains (220-230 V) or by a adaptor from the 12 Volt vehicle supply. The power adapters are supplied with this kit. The test equipment also comes complete with two Carrying Straps, one Earphone and several plastic bags and beakers for taking samples. The complete equipment is stored in a extremely strong airtight and watertight Aluminium carrying case. The equipment is supplied in Brand New condition.

Measurements Units: ?Gy/h or cGy/h (Intensity), in cGy (Dosage) oder CPS (Impulse).
Measuring Range: 0 to 999 cGy/h, 0 to 999 cGy or 0 to 9990 CPS.
Switch-able alarm threshold values in five steps (up to 20 or 100 ?Gy/h,0,1 or 1 or 10 cGy/h).
DM-21 Dynamotor for BC-312 / BC-314 WWII Radio Receiver
This is the DM-21 Dynamotor for the BC-312 or BC-314 Radio Sets. Supplied in NOS New Old Stock condition. There were plenty of these radios available on the surplus market back in the 50's and a many of these radios were modified over the years to run on mains voltage with a home made power supply. A new DM-21 Dynamotor would be a perfect for restoration of a radio to original specifications. The Dynamotor produces 235VAC @0.090 A from a 14VDC @3.3A power supply. It could also be used to provide HT voltage for other radios or projects.

RPM: 5400.
Input Volts: 14 VDC @3.3 Amp.
Output Volts: 235 Volts @0.090 Amps.
DOM-410 Geiger Counter
The DOM-410 Geiger Counter was used by Dutch, French and Belgian Army in the late 1970's early 1980's. It is manufactured to high standard under license from SRAT. It is hermetically sealed unit and water tight.

The Beta Gamma probe has a removable Gamma shield, and is quite large, giving it a sensitivity of roughly 1 CPS background. In the CPS mode, 1000 CPS = 1 mr per hour. It has 3 Time constants Rapide, Lent, Mesure and 3 ranges 10 CPS, 100 CPS, 1000 CPS. In the Gamma only mode, the selector uses the internal gamma compensated tube, which may be removed from the side of the unit, and placed at the end of a 20 foot cable for remote monitoring. In the mr per hour mode it uses the internal gamma tube to measure 1-1000 millirads per hour.

When switched to the Rad/hr mode, the internal or remote mounted gamma only tube will measure from 1 rad per hour up to 1,000 rads per hour. Overall, it is a very sensitive Geiger counter that is robustly built and designed to take allot of abuse.

The counter has a total range of 15&#956
