Alarming dosimeter and rate meter with data point tracking and optional software
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 that can be augmented
with the use of headphones.
The Xtreme boot offers maximum performance in a lightweight rugged solution for using
the Radiation Alert® Sentry in rugged conditions. The Xtreme boot is designed specifically
for individuals operating in tough environments, such as, Radiologists, 1st Responders,  Mining
and HAZMAT crews. Made of a RoHS compliant TPE rubber, the case also offers superior grip and
drop protection. The boot has a matte black finish identical to the enclosure of the instrument for
a seamless look, while giving the user complete access to the unit’s operation.
