1. It is made of premium material, silicone covered design, antislip and antidrop, wear resistance and with comfortable grip feeling.2. Adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation.3. Configured LCD color screen, with multifunctional monitoring pages, real-time display of current dose rate real-time value, cumulative measured value, cumulative stored dose rate, maximum value, average value, starting date, cumulative time.4. The detector is used to measure X, γ and β rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides.5. Three alarm modes design, with sound/light/vibrating alarm when dose rate and cumulative dose are over threshold, and the thresholds of dose rate and cumulative dose can be set manually.
