Features MULTIPLE FUNCTIONS: The nuclear radiation detector adopts sound and light dual indication, and has real time dose rate, average dose rate, cumulative dose rate, and trend chart functions. DETECTION ITEMS: This portable Geiger counter can detect X ray, γ ray and β ray, suitable for radiation dose detection of stone, jadestone, and various unknown minerals. CLEAR SCREEN: The nuclear radiation detector adopts organic light emitting diode screen with a 128x64 resolution, which is clear and intuitive, ensuring accurate reading. HIGH EFFICIENCY: Adopting M4011 J321 Geiger counter tube, the tube wall is sprayed with tin oxide as the cathode, with high sensitivity, for ARM processor, fast operation speed. APPLICABLE RANGE: The measurement range is 0‑500usv/h, widely used in where ionizing radiation exists, such as home radiation, irradiation processing enterprises, and hygiene.
