Features EXCELLENT PERFORMANCE: Measures nuclear radiation, detects sensitivity and ensures accuracy of measurement results. The detection range is from 00.08 μ Sv/h to 9999 μ Sv/h. MULTIPLE TESTS: Combined radiation tests of β, γ and X-rays. One machine for more, very practical equipment. ALARM FUNCTION: Geiger counter provides audible and visual alarms if radiation is detected. Allowing you to give an answer in time. EASY TO USE: With the rechargeable battery, the charging work of the nuclear radiator detector can be done via USB or car charger. SMALL AND LIGHTWEIGHT: The nuclear radiation monitor can detect the radiation level of any object or environment at any time, such as detecting radiation from toys, antiques, building materials, furniture, decorations, food, etc. 1.
