Gold & Silver Forum - Ludlum Model 14C Geiger counter offered..

I have a Ludlum Model 14C Geiger counter, and two Model 44-9 probes/detectors (detects alpha, beta, and gamma radiation).

I'm employed in the Nuclear field, and I have personally used this unit. It works flawlessly, has a recent calibration, and as you can see from the pics, the battery check is good.

Included is the counter instruction manual, detector (probe) instruction manual, and a check source to verify proper functioning. $250.00 shipping included. PM me if interested.

Thanks, tnhighwayman

LUDLUM MODEL 14C SURVEY METER DESCRIPTION/SPECIFICS:
The Ludlum Model 14C survey meter was designed to meet nuclear medicine requirements. The Model 14C is similar to the Model 3, but with an internal energy compensated G-M detector. It can be used with one or more external GM or scintillation detectors for alpha, beta, or gamma detection up to 0-200 mR/hr. This additional internal detector creates fifth high range of 0-2000 mR/hr in addition to the four ranges covered by the external probe. It is used in hosptials, universities, power plants and regulatory facilities. Standard scale is 0-2 mR/hr with five counting ranges: x0.1, x1, x10, x100, and x1000. (Dual scale cpm & mR/hr are available on request). Two �D� cells provide over 200 hours of operation. The Model 14C is supplied as shown with built-in speaker.
