Feature:1. HIGH SENSITIVITY: Nuclear radiation detector uses professional Geiger counters and advanced GM tubes as the core sensors, which can accurately detect , And X ray, updated once per second. The detection range of the radiation detector is 00.00 to 10mSv/hr.2. SOUND AND LIGHT ALARM: Regardless of whether the radiation detector screen is in a sleep or working state, when the detected radiation dose exceeds the alarm threshold, the geiger counter dosimeter will emit a sound and a flashing screen alarm. Take full care of your and your family's health.3. LOW POWER CONSUMPTION: Equipped with a powerful rechargeable lithium battery, the nuclear radiation detector only needs to be charged for 2 to 3 hours. After automatic sleep during operation, the monitor can continuously measure for 24 hours.4. PORTABLE: Small and convenient, you can carry a nuclear radiation detector anywhere you want to detect it. This radiation detector can provide you with 24 hour comprehensive detection.5. WIDE APPLICATION: This radiation dosimeter is widely used in existing ionizing radiation environments, such as home decoration, radiation production enterprises, health, nuclear laboratories, nuclear power plants, building materials, petrochemicals, geological surveys, etc. An ideal choice for families, hospitals, and workplaces.Specification:Item Type: Nuclear Radiation DetectorMaterial: ABSBattery: Polymer battery x 1Battery Capacity: 2000mAh (shipped with built in battery)Detector: Energy compensated GM counter tubeMeasurement Range: 00.00 Sv/h to 10m Sv/hDetection Ray Type: ray, X ray, rayRange: 15 to 24 hoursSuitable for Various Scenarios: Home, hospitals, nuclear power plants, laboratories, processing enterprises, metallurgy, etc..Package List:1 x Nuclear Radiation Detector1 x USB Cable 1 x Manual
