Radiation Metrology Detector X-ray/Y-ray/B-ray, six characteristics of quality from the inside out: high-definition display, accurate measurement, aluminum alloy body, multiple alarms, one-key operation, power saving and durability. Geiger-Miller technology tubes, high-sensitivity counting instruments for detecting the intensity of nuclear radiation (B-rays, Y-rays and X-rays). Imported aluminum alloy casing with two colors to choose from, breaks the traditional material, and the small body has a great effect. There are 4 reasons to choose us: GM counter tube is used, which is sensitive and ensures the accuracy of the measurement results; TFT high-definition display screen, instantaneous dose rate /Accumulated dose/average dose rate, easy to observe and read in different light environments; three alarm reminders, sound, flashing light, vibration, over-limit alarm reminder, timely alarm to ensure safety; built-in carp battery power supply, power saving and durable, Reusable, continuous measurement for 15~24 hours after fully charged. Applicable to multiple scenarios, and personnel are always available in multiple environments: households, nuclear power plants, hospitals, processing enterprises, laboratories, and metallurgy.
