Features:*Ultra-high sensitivity: high data accuracy. Automatic audible and flashing alarms when dose rate radiation dose exceeds threshold*High Detection Performance: Ultra-fast detection with low measurement error, Geigers radiation hardened detectors detect X-rays almost instantly, real-time updated radiation dose data and averaged at every second interval. * Wide range of uses: The radiation detector uses a 48mm Geigers counter tube, which can detect the radiation level of any or any environment at any time. Examples include radiation detection, antiques, building materials, furniture, food, etc. *Low Energy Consumption-OLED Display: Built-in powerful rechargeable-battery, the radiation detector only needs to be charged for 2-3 hours, and the display can continue to measure continuously for 50 hours after automatic sleep when working. *Portable design: small size, clip design, easy to carry.Notice:1.Actual color may be slightly different from the image due to different light effect2.Please allow 1-3cm deviation due to manual measurementMeasuring range: 0.05uSv~50mSvWorking environment: temperature -20C~50C; humidity
