This advanced radiation detector is a professional-grade instrument designed for precise measurement of gamma, beta, and X-rays using a Geiger-Müller counter. With a measurement range of 0 to 10 mSv/h and high sensitivity of 80 CPM/µSv, it provides accurate real-time monitoring of radiation levels. The device features a large 2.3-inch multifunctional display showing cumulative dose, average, and maximum readings, along with graphical representations. Dual alarm modes for radiation and cumulative exposure offer visual, audible, and vibration alerts for enhanced safety. Operating within an energy range of 48 to 1500 keV, this versatile instrument is ideal for research facilities, medical institutions, industrial applications, and radiation monitoring scenarios. The unit includes a micro-USB interface and rechargeable lithium battery with 1100 mAh capacity. Measuring 6.50 × 3.54 × 1.26 inches and weighing just 0.47 pounds, this compact device offers multiple display units and supports eight different languages. It operates effectively in temperatures from 32°F to 122°F with 5-70% relative humidity.
