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/cumulative dose/average dose rate. Easy to observe in low light environment, easy to read.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. Power supply: 3 AAA batteries (not included), or Type-c power supply. The external Type-C interface can be used for power supply.Notice:1.Actual color may be slightly different from the image due to different light effect2.Please allow 1-3cm deviation due to manual measurementDescription:Size: 11.6*6*3.5cmEnergy response: 48keV-1.5MeVPower supply: 3 AAA batteries (not included), or Type-c power supplyPower consumption: <150mW
