6.85-Year Battery Life
Operates continuously for over 6.85 years (60,000 hours) on a single 9V Lithium battery, or over 3.22 years on standard alkaline 9V.
100KB Data Logging
Stores up to 91,466 time-stamped measurement records autonomously without a PC, exportable in standard CSV format via USB.
24/7 Continuous Monitoring
Tracks Present, Average, Maximum, and Minimum dose rates with automated date and time stamps whenever a new peak reading occurs.
NIST Traceable Calibration
Can be calibrated to official NIST international standards of accuracy required for regulatory compliance work (Cs-137 calibrated).
Pulse LED & Audio Alarm
Features LED event flashing, 3-level audio clicker/alarm, programmable dose rate alarm, and headphone output jack.
