Features 1、Reliable Performance: This geiger counter nuclear radiation detector adopts a microcontroller chip and is equipped with a for tuya wifi module. The for tuya smart app is equipped with two mobile application apps, for Android and for iOS, and a 1.29 inch organic LED display screen. It automatically generates data documents and can store 10000 sets of data. The time, date, and sound alarm can be set, and the three main interfaces can be freely selected. The dark mode and day mode can be adjusted according to the environment, and the screen operation can rotate 180 ℃. 2、High Sensitivity: The nuclear radiation detector uses professional Geiger counters and advanced geiger tubes as the core sensors, which can accurately detect β, γ and X ray, updated once per second. The detection range of the radiation detector is 0~9999mSv/hr. 3、Sound and Light Alarm: Regardless of whether the individual radiation detector screen is in a sleep or working state, when the detected radiation dose exceeds the alarm threshold, the Geiger counter dosimeter will emit a loud sound and a flashing screen alarm. Take full care of your and your family's health. 4、Low Energy Consumption: Equipped with a powerful rechargeable lithium battery, the nuclear radiation detector only needs to be charged for 1 to 2 hours. After automatic sleep during operation, the monitor can continuously measure for 24 hours.The nuclear radiation detector is compact and convenient, so you can carry it anywhere you want to explore. This radiation detector can provide you with 24 hour comprehensive detection. 5、Wide Application Range: This wifi nuclear radiation detector is widely used in existing ionizing radiation environments, such as home decoration, radiation production enterprises, health, nuclear laboratories, nuclear power plants, building materials, petrochemicals, geological surveys, etc. It is an ideal choice for families, hospitals, and workplaces.
