The Radiation Alert® Sentry EC is a personal alarming radiation dosimeter and rate meter, designed to safeguard personnel working in environments with potential X-ray or gamma exposure.
This pocket-sized unit features an energy-compensated tube for a linear gamma response and built-in memory for tracking accumulated exposure data. With the free SentryCom Software, you can easily generate incident reconstructions for analysis and set custom vibrating and audio alerts for dose (>1.0 mR/10 µSv) and dose rate (>1.0 mR/hr/10 µSv/hr).
An audio switch allows you to choose between audible clicks with each detected count or a discreet silent mode.
