This working Geiger Counter is a hobbyist assembled combination of an Eberline 3212679 laboratory grade instrument and an ex-military "RADIAC DETECTOR DT-53B/PDR-27" probe. The meter has four ranges of scaling and an earphone BNC connector is on the front panel.  All scales, high voltage and threashold sensitivity are independently adjustable. The probe has a manually shiftable window cover which clips to the probe body in both open and closed positions. This is an uncalibrated meter.  It will run for a very long time on 5  "D" size flashlight cells. Photos two shows the background reading and photo three is the indication from a pair of radioactive lantern mantles. (A very slight adjustment of the high voltage can be made, if more sensitivity is needed.) The probe cable is about 55 inches long, and permenently attached inside the unit.  This makes battery changing less convenient, but otherwise seems to work OK.  I cannot provide any assurance that this unit is fit for a specific use, only that it appears to be in working order. Shipping quoted is to the continental U.S. only.  Thanks for looking!
