Short description:

The Ludlum Model 14C is a rugged, handheld analog Geiger counter designed for alpha, beta, and gamma radiation surveying. It supports both an internal GM detector (0–2000 mR/hr range) and external GM or scintillation detectors via a Series “C” connector. Durable cast aluminum housing with handle and locking clamps ensures long-lasting reliability in industrial or laboratory environments. The unit bears a calibration seal (“Calibration Void If Seal Is Broken”), though the exact date of calibration is not available.
