AS PRICE OF DP66 WENT TERRIBLY UP- TO FACE NEEDS OF OUR CUSTOMERS,WE MANAGED TO GET A NEW MILITARY DP75 COUNTER FOR A GREAT SELLING VINTAGE GEIGER COUNTER ON . MOST OF THEM WERE LAST INSPECTED IN LAB IN 2006-2009. READINGS ARE OK DESPITE OF SO MANY YEARS AND IT WILL SERVE YOU FOR YEARS! PROJECTED TO SURVIVE NUCLEAR WAR AND ELECTROMAGNETIC PULSE.
I AM SORRY BUT HAD TO INCREASE THE PRICE. THAT ARE LAST WORKING UNITS AVAILABLE ON THE MARKET. SO IT LOOKS LIKE AFTER THIS 2 YEARS OUR ADVENTURE WITH THEM IS ON THE FINISH :( 4 TONES SOLD NOT JUST ON TESTIFY THAT IT WAS A GOOD COUNTER DESPITE SO MANY YEARS AFTER ITS PRODUCTION...
Fully working and tested! Great and advanced set. Date of production is 1968-1974
full instruction in English is here:
DP-66 is a Polish military rentgenometr produced in the 70s, is an enhanced version of the well-known DP-66, among others has been changed structure of the probe were also installed for better quality components such as capacitors and newer silicon transistors. Has been changed as the headphone jack, which allows now counting the quantum of radiation.
As per device military DP-66 is terribly sensitive, there is no problem with measuring the background radiation or construction materials, thanks to the use of up to 3 meters geiger that have been placed in the probe, are CTC-5 for the sub-VI, V and IV, then DOB-80 for range III and Dob-50 for sub-ranges II and I, choose a sub is made rotary switch, supporting a plate rating. By using three tubes measuring range is much more extensive than typical dosimeters, the first sub-we can measure up to 200R / h, which is about 200,000 times more than previously described dosimeter Master-1, in addition to measuring such high radiation intensity, we can also measure these much lower as background radiation or cosmic rays, just set the sub to VI or 0,05mR / h - 0.5mR / h.
Reading the radiation intensity is carried out by reading labels and the location of its guidance if it is too dark and you have problems with reading, we can retrieve up by pressing the "SPOTLIGHT" lights up when a light bulb, which also shed light tablet that provides a comfortable reading after turning off lighting (plate was covered with paint periodic illumination)
The probe is made of aluminum, has a rotating body, if we want to just measure the gamma leave her twisted, for measuring beta unscrew it, then you get us a window where you can see a well-known measure of CTC-5 .
Roentegonemeter also has the ability to reset personal dosimeters DKP-50, a headphone jack, so that we hear, each particle of which will go to the tube. The device is powered by two batteries R20, which is sufficient for about 70h of work or through an adapter for external power supply.
