Features: *High-quality material: The product is made of high-quality material, durable and wear-resistant, not easy to break, and can be used for a long time. * High sensitivity: The radiation detector uses advanced GM-counting tube as the cores sensor, which can accurately detect β, γ and X-rays to ensure the accuracy of the measurement results. When the detected radiation dose exceeds the alarm threshold, the radiometer will emit a loudly sound and flash the screen to alarm. *Easy to use: Equipped with rechargeables battery, digital display and touch screen buttons, convenient for you to use, light and compact, you can carry it with you. *Exportable data: This measuring instrument can output 10000 sets of data, even after power off, the accumulated measuring instrument, dose rate alarm threshold and other data will not be lost. * Wide range of applications: Radiation dosimeters are widely used in places with ionizing radiation environments, such as home decoration, irradiation production enterprises, sanitation, building materials, petrochemicals, geological surveys, etc. Radiation dosimeters are ideal for homes, hospitals, and workplaces.
