Feature: 1. POWERFUL FUNCTION: Nuclear radiation detector adopts dual indication of sound and light, and has functions such as real time dose rate, average dose rate, cumulative dose, trend chart, etc. Detect X rays, γ Ray, hard β. Radiation can be used to detect radioactive doses of marble, antiques, Japanese seafood, iodine 131, medical equipment, and various unknown minerals used in decoration. 2. USER FRIENDLY: Handheld nuclear radiation monitor, clear page, simple operation, covering two measurement alarm methods and recording modes. Accessible to people with disabilities. 3. EXCELLENT PERFORMANCE: The screen adopts an STN screen, with a screen resolution of 128X64. The core sensor uses a tin oxide cathode geiger counter tube, which has high sensitivity. The processor uses an ARM processor, which has fast computing speed and powerful processing functions. 4. APPLICATION: Widely used in household radiation, irradiation processing enterprises, health and epidemic prevention, and other environments where ionizing radiation exists, and where individuals receive radiation dose supervision and protection. 5. EASY CARRYING: Compact size and lightweight make the geiger counter easy to carry for convenient use, choose with confidence!
