Description
The Radiation Alert® Sentry EC is a compact personal alarming dosimeter and dose-rate meter for continuous monitoring in environments where gamma or X-ray exposure may be present. Its energy-compensated GM tube measures accumulated dose and dose rate, while built-in memory supports exposure review through SentryCom software.
- Dose-rate range: 0.1 to 15 R/hr (1 µSv/hr to 0.15 Sv/hr)
- Accumulated-dose range: 0.1 to 65 R (1 µSv to 0.65 Sv)
- Energy response: down to 20 keV
- Typical accuracy: ±15% of reading with Cs-137
- Customizable audible and vibrating dose and dose-rate alarms
- Mini-USB output for data transfer
- Power: included 9-volt alkaline battery; approximately 1,500 hours at normal background
- Temperature range: 14°F to 122°F (-10°C to 50°C)
- Weight: 8.6 oz. (243 g)
- Size: 4.2 x 2.7 x 1.1 in.
Includes NIST calibration, 9-volt battery, USB cable, and free SentryCom software download.
