The Sentry EC - Personal Alarming Dosimeter and Rate Meter
y x
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.

(Click the screen capture above for a larger view)
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.
