We are selling Vintage never-used Radiation Detection Meters that turn on once the batteries are installed. (Batteries are Not included) We do not confirm their ability to read radioactive material.
These are sold as conversation pieces and novelty devices - nothing more.
We (the seller) will Not be held responsible for anyone who foolishly exposes themselves to any radioactive material.
Each Unit will be Power Tested before packing and mailing
A power test is merely putting the three proper batteries in each unit and making certain it turns on and the meter level is adjustable. We Do Not have any radioactive material to test the sensitivity of the meter.
We wish to be clear - These units which were new at the time they were purchased in surplus from US Civil Defense - we are unboxing each unit placing (2) standard US domestic “D” cell batteries and a (1) European/Asia origin “B” cell 22.5 volt battery in each sold unit to confirm that it turns on and the sensitivity needle can be adjusted.
If the buyer wants to check to see if the unit can recognize and measure radioactivity It is up to the buyer (and not the seller) to safely find a radiation source to provide the final readings.
We are Not advising or instructing anyone to put themselves in danger or exposing themselves to a dangerous radioactive environment, and we will Not be held responsible for anyone who does expose or injures themselves to a radioactive element.
The Estate is in possession of over 1000 units which were all purchased unused in a Salvage Sale

A survey meter is an instrument that, using an ionization (ion) chamber, measures the rate of radiation. It is commonly compared to the speedometer of a car. Of the survey meters, the only ones you should look for is the CD V-710 medium-range survey meter, and CDV-715, CD V-717, and CD V-720 high range meters. There is only one medium-range survey meter, the CD V-710
You should not pay more than - for an uncalibrated CD V-710 Model 4 or 5. The only reason for this higher price is because of the collector value of the meter. For a calibrated CD V-710, you should only pay about 0-0.
