High Sensitivity - The nuclear radiation detector uses a professional Geiger counter and an advanced GM tube as the core sensor to accurately detect beta, gamma, and X-rays, updating every second. - Detection range: 0.0550 mSv/hr. Automatic Alarm - If the detected data exceeds the preset value, the device supports two alarm methods: audible and visual alarms, making measurements more convenient. Low Energy Consumption - Built in a powerful rechargeable lithium battery. - Charging time is 2-3 hours. - The display can continue to measure for up to 50 hours after automatic sleep when in operation. Alarm behavior and safety - When the radiation dose detected exceeds the alarm threshold, the detector will alarm with a loud sound and a flashing screen, whether the display is asleep or active. - All round care for you and your family. Use scenarios - Home monitoring: check background radiation levels during home renovations, in basements, or near potential sources of radiation to ensure safe living conditions. - Workplace safety: monitor exposure near diagnostic imaging equipment, labs, or construction sites to stay within safe limits. - Travel and on the go: carry during trips to areas with uncertain radiation levels or temporary work sites to verify portable exposure levels.
