Features:Ultra-high sensitivity: high data accuracy. 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 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, easy to carry.
