The Radiation Alert Sentry EC 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 an energy compensated tube for a linear
response to gamma and built in memory for recording data points for
tracking accumulated exposure. The SentryCom 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 with each
count recieved or a discreet silent mode.

The optional SentryCom Software enables you to easily integrate The
Sentry into your radiation safety program by allowing you to select
the thresholds for dose and dose rate alarms/warnings. You can set
the Cal Factor, and the data logging frequency, and download the
accumulated dose data as a text file. The report includes a
delimited time and date stamp, exposure, and power cycle
identifiers for easy recording and incident analysis in most
spreadsheet programs. Units of measurement can be changed between
mR/hr and μSv/hr to fit your application and reporting needs.
The SentryCom Software comes complete with mini-USB cable.
NOTE: Some older operating systems require access to Windows Update to
download the standard USB-Serial drivers to connect to the Sentry
EC with the provided USB cable.
