Features1. Nuclear Radiation Detector: This product is a small, highly sensitive radiation dose alarm device mainly used for monitoring X Radiation. It has the characteristics of high sensitivity and accurate measurement.2. Powerful Processor: Choose a high-performance microprocessor, which is easy to operate, convenient, user-friendly, and has strong anti-interference ability.3. Multi Function: This radiation detector has multiple functions, including a clear color screen, timed measurement function, over dose alarm, calendar clock function, sensor fault reminder function, automatic alarm function, calibration function, and multiple functions that are convenient for your use.4. Intelligent Alarm: Enter the alarm setting option and set the current dose alarm value and cumulative dose alarm value. Whether the detector screen is in a sleep or working state, if the detected radiation dose exceeds the alarm threshold, the radiation monitor will automatically alarm. Both light and sound alarm methods are freely selectable.5. Widely Used: Used in ionizing radiation environments and environments where the human body receives radiation dose supervision and protection, such as home decoration, radiation luminescent manufacturing enterprises, health, nuclear laboratories, nuclear power plants, building materials, petrochemical industry, geological surveys, steel use, industrial testing, etc.Specifications: Material: plastics Battery: 1 * 3.7V 1500mAh battery (included) Measure range: 0.05uSv-50mSv Measure precision: -17% to +25% based on 137Cs Durable time: 20 days (continue measure and not open pellet sound) Recharging joggle: Type-C joggle (green lamp normally lights up when recharging, extincted after fully charged) Alarm responding time td: <10s Typical power consumption: 13mW Alarm threshold deviation: -17% to +25% Working temperature: -20 to 50 Working humidity: 95%RH no condensation Size: 12 x 7 x 3 cmWeight: 402 gPackage Include:1x Electromagnetic Radiation Detector 1x Rope 1x Instruction 1x USB Cable 1x Storage Bag
