The Radiation Alert® Sentry is a Personal Alarming Dosimeter / Ratemeter designed to ensure the safety of personnel that work in occupations with potential x-ray or gamma exposure.
The pocket sized unit has built in memory for recording data points for tracking accumulated exposure. The Sentry Software option 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 and dose rate.
Use the audio switch to choose between audible clicks or a discreet silent mode. The Sentry can be augmented with the use of headphones.
