Sentry EC
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 an energy compensated tube for a linear response to gamma and built in memory for recording data points for tracking accumulated exposure.
The included 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 recieved or a discreet silent mode.
SentryCom Software
The free SentryCom Software enables you to easily integrate The Sentry into your radiation safety program by allowing you to select the thresholds alarms/warnings to your desired levels for dose (>1.0 mR/10 μSv) and dose rate (>1.0 mR/ hr/10 μSv/hr). 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.
