This listing is for one used Ludlum Model 3 survey meter Geiger counter with a Ludlum 44-7 Alpha, Beta, Gama sensitive end window probe as well as a small mounted Carnotite test specimen. This Geiger counter was calibrated in 2001 and still matches readings of a Johnson Nuclear survey meter with a similar probe calibrated in 2008. Documentation from last calibration is attached. This Geiger counter is in good working condition and it has new batteries. It has some minor scratches in the paint. I got this Geiger counter as laboratory surplus. I run a gem and mineral business and have used it for the last few years. It is perfect for gem and mineral collectors as well as paleontologists. This Geiger counter is very sensitive but also scales up to levels that affect human health making this Geiger counter very useful for monitoring food and or radiation levels in a nuclear disaster event. I will ship this item overseas. This Item AS IS!!!
