Features Fast Response The monitor responds quickly to radiation and emits an alarm in a high risk environment in a timely manner, providing high flexibility to measure the ambient background and update the detected values in real time. HIGH ACCURACY AND SENSITIVITY The detector is used to measure β-γ and X-ray radiation, which is best suited for measuring small changes in radiation level and is highly sensitive to the most commonly used nuclides. Wide Application This tester can detect electromagnetic radiation and nuclear radiation, meet the requirements of detecting family life, detecting substations, detecting mobile iron towers, etc. Intuitive display: The Geiger counter has a large colour screen that is more intuitive and convenient when viewing data, and allows you to read real-time values easily and quickly. And the buttons are easy to use. Portable Size This tool is compact and very convenient for daily use. You can carry it in the tool bag without taking up too much storage space.
