The DP-66(M) is another rare and unusual piece of Cold War history, this time from the
other side of what used to be the Iron Curtain. It is one of the Warsaw Pact's closest equivalents
of the CDV-700, but with a lot more features. We have a very small number
of units available and as an added bonus each one comes with one of our exclusive speaker modules and 3.5mm jack adaptor plugs. Also, for a short time, while stocks last, we will include a free purpose designed DP-66 earpiece
The DP-66 and DP-66M* are Polish made upgrades of the
classic Russian DP-5V Geiger Counter (featured several times in the excellent Chernobyl TV mini series), but it uses more up-to-date (and reliable) components
and unlike that old Soviet jobby, it is powered by two readily obtainable 1.5
volt 'D' cells torch batteries that can keep it running for 60 hours or more.
However, what makes this instrument so special
is the fact there are three Geiger tubes inside the hand-held probe. These are
sensitive to a very wide range of Beta, Gamma and X-Ray radiation, from normal background to don't plan on reaching retirement age...
Measurements are shown in counts per minute (0 - 10,000 cpm) Roentgens/milli Roentgens per hour (0.5 mR/h - 200R/hr) in 6 selectable ranges. The probes have a 3-mode rotating shield, for discriminating between Beta and Gamma, or high/low range Beta and Gamma. The DP-66 also has a built-in charger for a DKP-50 quartz fibre pen dosimeter (not included).

The large moving coil meter has a luminous
dial, it's also backlit, which can be handy for a spot of night time detection. Our specially designed 3.5mm jack adaptor, which comes with the speaker module, can also be used to connected the unit to ordinary headphones, an amplifier or even a PC, running counting or logging software.
Although the control labelling is in Polish it's is incredibly easy to use. The main
selector switch has 8 positions, for power off ('W'), battery check ('K'); the
other 6 positions select the operating range. The only other controls are two
buttons -- for turning on the meter backlight and zeroing the meter - and a
small knob for zeroing a pen dosimeter when it is inserted into the charging
socket on the top panel. Don’t worry, there is a English translation of the
manual on the web which you can download
The DP-66/Ms that we have are now over 40 years
old but most of that time was spent in long-term storage. They
show slight some signs of use due to periodic testing and calibration but the
overall condition is generally very good and before shipping they are thoroughly
checked, cleaned and where necessary refurbished.
* the DP-66M variant has a slightly different probe design with a 'pop-up' Beta shield instead of the rotating type used on the standard DP66 (pictured). In virtually all other respects they have an identical specification.
