High-Sensitivity Dose Alarm for Nuclear & Lab Environments
Ensure precision and safety in radiation-prone workspaces with the High-Sensitivity Dose Alarm for Nuclear & Lab Environments. Engineered for professionals working in nuclear power facilities, research labs, radiology departments, and medical imaging centers, this advanced dose alarm delivers ultra-accurate real-time radiation monitoring.
Equipped with a high-precision Geiger-Müller tube, the device tracks gamma and X-ray radiation exposure with exceptional sensitivity, displaying both dose rate and cumulative dose on a crisp digital screen. Visual, audible, and vibration alarms alert users the moment radiation levels approach set thresholds, making it an essential tool for safety compliance and exposure control.
Key Features:
High-Sensitivity Detection: Captures even low-level radiation changes for maximum safety assurance.
Dual Display: Real-time dose rate (µSv/h) and accumulated dose for detailed monitoring.
Multi-Mode Alerts: Loud audio, visual alarms provide instant exposure warnings.
Professional-Grade Build: Compact and robust, designed for rigorous use in clinical and industrial environments.
Replaceable battery Convenience: Relaceable AA battery delivers long-lasting performance.
Smart Threshold Settings: Customize dose and dose rate alarm levels to meet your operational standards.
