Personal Alarming Dosimeter & Rate Meter

The Radiation Alert® Sentry EC is a Personal Alarming Dosimeter / Rate Meter 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.

SentryCom Software

The Windows® based SentryCom Software enables you to set the values for dose and dose rate alarms and warnings, set the Cal Factor and the data logging frequency. It also allows the user to download the accumulated exposure data which includes time and date stamp, exposure and power cycle identifiers for analysis. The data is stored in a convenient delimited text file for use with a spreadsheet program.

The Radiation Alert® Sentry EC now has the FREE SentryCom Software available for download from the factory website. You can now download accumulated exposure and make changes in each unit for Alarm and Warning values. Go to the following link to download the software for the SentryEC:
