High-Sensitivity Radiation Detector for Laboratory & Field Use
Engineered for precision and versatility, the High-Sensitivity Radiation Detector for Laboratory & Field Use is the ideal tool for professionals who need accurate, real-time radiation monitoring in both controlled and rugged environments. Whether you're conducting research in a lab or performing on-site inspections in the field, this advanced detector delivers reliable measurements of gamma and X-ray radiation with high sensitivity and speed.
Built around a high-precision Geiger-Müller tube, this device offers real-time dose rate and cumulative dose tracking, clearly displayed on an easy-to-read digital LCD. It features audible, visual, and vibration alarms that trigger instantly when radiation levels exceed user-defined safety thresholds. Compact, rechargeable, and user-friendly, this detector combines laboratory accuracy with field-ready durability.
Key Features:
High-Sensitivity Detection: Detects even low-level gamma and X-ray radiation with precise accuracy.
Real-Time Readings: Displays current dose rate (µSv/h) and total accumulated dose.
Multiple Alert Modes: Instantaneous audio alarm, flashing LED, and vibration for immediate awareness.
Lab-Grade Precision, Field Durability: Suitable for sensitive lab environments and rugged outdoor use.
Rechargeable Battery: Long-lasting lithium battery charges via USB for up to 130 hours of operation.
User-Adjustable Thresholds: Customize dose and rate alarms based on your safety requirements.
