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. 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.
