It’s another rare opportunity to get your hands on a piece of Cold
War history, this time from the other side of the Iron Curtain. The
DP-66 was one of the Warsaw Pact’s equivalents of the CDV-700, but
with a lot more features.
First the basics. Inside the hand-held probes there are three Geiger
tubes, sensitive to a very wide range of Beta, Gamma and X-Ray
radiation. Measurements are shown in counts per minute (0 – 10,000
cpm) Roentgens/milli Roentgens per hour (0.5
mR/h – 200R/hr)
The probes are fitted with either a 2 or 3-mode rotating shield -- see photos**. This is for discriminating between Beta or Gamma, or high/low range Beta and
probes can also be
used with a
supplied telescopic extension pole, for
detecting ground-level sources, in hard to get at places, or for keeping potential sources at

so you can listen
the clicks. We've also developed a 3.5mm jack adaptor, so it can be connected to ordinary headphones, a custom version of our mini speaker and LED flasher module, or ordinary stereo headphones.

a small knob for
zeroing the pen dosimeter when it is inserted into the charging
socket on the top panel.

they are in pretty good, usable, condition and
still capable of protecting the instrument, probe and
