Updated High Sensitivity: The nuclear radiation detector uses complex GM tubes and professional Geiger counters as its core sensors, enabling it to detect beta, gamma and X-ray radiation accurately and in real time. Radiation detector detection range: 0.08 to 50 mSv/hr. In addition, both average and cumulative dose values can be recorded. Two measurement modes: You can set the "measurement time" range from 0 to 999 hours on the digital nuclear radiation detector, which includes real-time data update and timing detection functions. The nuclear radiation detector will automatically store the latest 10 timing measurement data. Standby for 14 days. Intelligent alarm: the alarm value can be programmed. When the recorded radiation dose exceeds the alarm threshold, regardless of whether the personal radiation detector screen is active or in sleep mode, the Geiger counter dosimeter will emit a loud sound and a flashing screen alarm. UPDATED CONVENIENT DESIGN: In this personal dosimeter radiation detector, you can additionally control other settings to meet your needs. For example, the ability to establish data logging, deletion, alarms, units, sounds, system clock and sleep preferences. Wide range of applications: This radiation monitor is often used in ionizing radiation environments. Widely used in household radiation, irradiation processing enterprises, sanitation and epidemic prevention and other environments with ionizing radiation, as well as personal radiation dose supervision and protection occasions.
