The Radiation Alert Monitor4EC Analog-Based Ionizing Radiation Detector is a compact, general purpose survey meter that is capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges. For each event that is detected, a red count light flashes.
This radiation survey meter features an analog display, versus other more expensive digital devices. The accuracy is typically plus-or-minus 15%, and the Radiation Alert MONITOR4 offers a more linear reading for gamma and x-rays (above 40 keV).
This review is for the Monitor4EC Radiation Detector, which is the newer, more ergonomic design than the Monitor4. »
