DP-75 GEIGER COUNTER BETA GAMA RADIATION DETECTOR DP75 FULLY WORKING

Fully working!

Fully tested and working! 0.05 mR/h – 500R/h.

I AM SURE THIS GEIGER COUNTER WILL BECOME THE BEST SELLER AS OUR DP66

WE MENADGED TO BUY MORE OF THESE SAME IN GREAT CONDITION SO WE KEEP THE OLD 

PRICE! 

AND NOT GETTING CRAZY LIKE SOME OTHER SELLERS. THEY HAVE BEEN IN SERVICE

DURING COLD WAR THAN HAVE BEEN IN SERVICE IN NATO AND NOW THEY WILL SERVE TO US!

Most of these were LAB Inspected between 2003 and 2013. All readings are 

correct, they were fully calibrated in POLON Laboratory, and when I test 

them before dispatch with my original source the readings are OK.

I am sure these will give reliable service for many years. Ideal for civilian use, 

collectors of cold war ephemera, universities, museums or even for resale.

The most advanced of military Geiger counters used in LWP (Polish army 1943-1990) . In many places, still in use today , although it has been gradually replaced by the newer types . Compared to the DP - 66 it has a signalling threshold, an extended maximum range of 200 to 500 R / h , has introduced a leatherette case, increased the number of batteries R-20 (D) from 2 to 3 and added an external power supply possibility, which can enable connection to any power source voltage between 10 and 30 V (very useful). I offer you a professional modern roentgenoradiometr DP-75. In comparison to the DP-66 the DP-75 uses newer components, silicon transistors, higher quality capacitors as well as an adequate level headphone output can be used for pulse counting. The instrument is equipped with newer types of transducers, the DOI30 and DOI80.The instrument is designed to measure radiation in the 0,05mR / h - 500R / h. The device has 7 measurement sub-ranges. NOTE: Because the device is super sensitive on the most sensitive range (sub-7) this 0,05mR / h - 0,5mR / h it measures background radiation and is suited to checking the radioactivity of minerals, building materials, etc. Most of the higher military measures will be useful only in the event of nuclear war. Specifications of the instrument:- Measuring range 0,05mR / h - 500R / h divided into 7 sub-ranges; Supply 4.5V (3 batteries R20 “D” cell) or external power supply with a DC voltage of 10 to 27 V.; External probe for the measurement of beta-gamma; Headphone acoustic output for control (or counting) quantities of radiation.

You are buying a set consisting of:- Instrument with case and probe- Wooden transit suitcase 47 x 16 x 25 cm; Weight: 7.5 kg; Extension telescopic probe; External power supply cable- A scan of the instruction manual with circuit diagrams.
