Features: Multifunctional Geigers Counter: Used to detect the intensitys of ionizing radiation (γ β, and X-rays). Ultra-high sensitivity: high data accuracy. Automatic audible and flashing alarms when dose rate radiation dose exceeds threshold. High-definition display: display instantaneous dose rate/cumulative dose/average dose rate. Easy to observe in low light environment, easy to read. 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. Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Body material: aluminum alloy Size: 1.6*2.7*10.5cm Screen size: 0.96 inches Detection and counting: 48mm Geigers counter tube Battery capacity: 400mAh Battery life: 15-24 hours Charging time: 1 hour Charging method: USB-type-c Package List: 1 x Nuclears Radiation Detector
