Have questions about buying this product?
The Radiation Alert® Sentry EC is a Personal Alarming Radiation Dosimeter & Rate Meter. This model is designed to ensure the safety of personnel that work in occupations with potential x-ray or gamma exposure.
The pocket sized unit has an energy compensated tube for a linear response to gamma and built in memory for recording data points for tracking accumulated exposure. The free SentryCom Software enables you to generate incident reconstruction for analysis. The software also permits you to easily set the vibrating and audio alert to your desired levels for dose (>1.0 mR/10 µSv) and dose rate (>1.0 mR/hr/10 µSv/hr).
Use the audio switch to choose between audible clicks with each count received or a discreet silent mode.
