Pocket Size Exposure & Count Ratemeter

The Model 2401-EC instrument is a pocket size radiation detection meter with an integrated energy compensated GM tube for measuring gamma exposure. The meter measures 0-200 mR/hr exposure rate and also 0-210,000 cpm via separate scales. The metal case offers excellent protection against abuse. The overall size and integrated design facilitate ease of use.
