- Nuclear Radiation Detector: uses a Geiger counter and energy compensation GM tube as the core sensor, accurately detecting beta, gamma and X-rays. Features fast detection, strong anti interference, high sensitivity, wide measurement range and long service life. Detection range: 0.08 uSv/h to 9999 uSv/h. Radiation dose data updated in real time every second. - Intelligent alarm: cumulative dose value and dose rate alarm value can be set arbitrarily. When the radiation value exceeds the set threshold, the dosimeter emits a loud sound and the screen flashes to alarm, helping to avoid radiation risks in daily life. Main technical indicators comply with international standards. - Application fields: in living environments such as food, water, imported goods, cosmetics, stone and decorative materials; in medical environments including radiology, CT, CR, DR, radionuclides, pharmaceuticals; in industrial environments such as nuclear power plants, metallurgy, waste recycling, metal casting. Personal protection uses include regulatory, customs, medical, maternal health and occupational health. - Easy to use: start with one click and begin measuring immediately. GM counter ensures measurement accuracy. Built-in 400 mAh rechargeable lithium battery provides 12-25 hours of continuous use after a 1 hour charge. Portable, compact, lightweight and easy to carry.
