Feature:1. INTELLIGENT ALARM: Whether the screen is in sleep or working state, when the detected radiation dose exceeds the alarm threshold, our radiation monitor will automatically alarm.2. 3 ALARM MODES: The radiation detector has three combined alarm modes of light, vibration, and sound to choose from, making it more effective.3. GEIGER COUNTER: Using a Geiger Muller counter, this radiation monitor can be used to detect the strength of ionizing radiation (, gamma, X rays).4. REAL TIME DISPLAY: Dose rate displayed per second, protective alarm response less than 5 seconds, ensuring accurate and reliable results.5. WIDE USAGE: Widely used in environments with ionizing radiation, such as home decoration, geological survey, iron, testing vehicles, nuclear power plants, industry, radiology, radiology laboratories.Specification:Item Type: Radiation MonitorMaterial: ABSModel: NR 950Detection Ray: , X and hard raysDetector: Energy compensated Geiger counter tube, with improved low energy responseNormal Content Standard: Within 0.5uSv/hMeasurement Range: a: Dose equivalent rate: 0.00~1000Sv/h (maximum 10mSv/h)b: Cumulative dose equivalent: 0.00Sv~500.0mSvEnergy Response: 48KeV~1.5MeV 30% (for 137Cs-)Relative Inherent Error:Model: NR 950 type 3% (137CS1mSv/h)Sensitivity: 80CPM/uSv/h (for Co-60)Alarm Threshold:a.
