Restored, Calibrated, MINT ENI CDV-700 / 777 Kit (Comes with extra tested & working 715, 750 pen charger and dosimeter pens) You are viewing a very nice Victoreen 777 Kit. The CDV-700 Geiger counter is a near mint ENI 6b with a custom made voltage regulator. (no worries about the old VRs failing). Fully restored & calibrated to original specs. Accurate within 99% +/-. Components replaced during rebuild are a better quality than original factory components. Some are military spec grade. Externally and internally this is very clean unit. I do not restore units which had batteries left in. The 715 passes self test and had a bench calibration. It zeros well except on setting 2 or 3 it is a little high. I am basically throwing this in for free and it will work in a cruch but, if the needle is moving on that bad boy, you best be running for the shelter. I cannot get components to rebuild these so I do not, nor do I warranty the 715s. The 750 Dosimeter works perfectly and I am throwing that in for free because they are actually quite useful. I clean the contacts, do bench tests and if they pass I ship them off. All the pens for the dosimeter zero and hold. The 715 is a model 1A "R" which means it had the revision back in the day. Everything in the photo is included including headset, strap, all manuals and certification sheet for the warranty CDV-700 (see below). The CDV-700 series meters are meter to get. They are used when users need to detect of any level of radiation near, or from far away. This includes: disasters in distant lands, foods, pets, debris, even people. They can be used for oil well pipe inspection, mineral mining, and more. Can be used to check persons undergoing radiation therapy. If beta or gamma radiation (most common) becomes attached to something, this will detect it. The CDV-700 can also be connected to a PC using CDV click counting software using a audio adapter (see other ebay seller for the software package). In my opinion being EMP proof, waterproof, rebuildable and rugged, this is the most valuable radiation detection meter one can own. Again the 700s are rebuilt here and ready for decades of hard work or standby. Other meters are cleaned and functioning but do not carry the same warranty as the ENI CDV 700. Under normal use I warranty the 700s for life. Calibration: We adjust the gauge needle, followed by high voltage adjustment using the supplied the GM tube combined with supplied voltage regulator. When needed on ENI units we make new zener strings (voltage regulator). We then adjust current flow to the gauge needle using several known check sources (gamma and beta). Calibrations were checked against $10k hospital machines and were found to be 100% accurate. Kit Features: Mint ENI CD V 700 with Fresh Calibration using Lab Standards Working 715, and 750 Dosimeter - Units were cleaned and tested only Dosimeter pens were tested and all passed Waterproof Design EMP Proof Design Rare Pile of matching / Awesome USA made Manuals (CDV 700) Lifetime Warranty Headset Strap All manuals Included Certificate of calibration with schematic PS - check out the low serial# !! This has collectors value also CDV 700 units are restored by: Replacing all audio, gauge & power diodes Replacing high voltage diodes Replacing all electrolytic capacitors Replacing all power supply capacitors Replacing all transistors Testing all voltage regulators for range Greasing rubber seals Testing all GM tubes Adjusting the high voltage (VR swap/calibration) ENIs have a modified Voltage regulator Stable at 925V Adjusting gauge needle (calibration) Adjusting tube/gauge needle sync (calibration) CDV-700s are increasingly difficult to find.
