Features MAIN PURPOSE: Portable nuclear radiation detector with high accuracy and sensitivity, the measurement range is 0.05uSv‑50mSv, can be used to monitor X-ray, β and y rays. GOOD PERFORMANCE: The microprocessor with powerful performance is selected and equipped with a TFT2.0 color screen, which is easy to use and has less interference. ALARM METHOD: Arbitrary combination of sound and flash alarm methods, and the alarm threshold can be set arbitrarily, when the threshold is reached, an alarm will be issued in time. MULTIPLE FUNCTIONS: With real-time monitoring, automatic alarm to standard and fault self-check function, the support time measurement can be set arbitrarily between 00-999 hours. APPLICABLE SCENES: Widely used in radiation for home improvement, nuclear laboratories, petrochemical, geological census, radiation dose supervision and protection of individuals.
