Features:Multifunctional Geigers Counter: Used to detect the intensitys of ionizing radiation ( , 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 or cumulative dose or 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 effect2.Please allow 1-3cm deviation due to manual measurementBody material: aluminum alloySize: 1.6x2.7x10.5cmScreen size: 0.96 inchesDetection and counting: 48mm Geigers counter tubeBattery capacity: 400mAhBattery life: 15-24 hoursCharging time: 1 hourCharging method: USB-type-c
