1、INTELLIGENT ALARM: Whether the screen is in sleep or working state, when the detected radiation dose exceeds the alarm threshold, our radiation monitor will automatically alarm. 2、3 ALARM MODES: The radiation detector has three combined alarm modes of light, vibration, and sound to choose from, making it more effective. 3、GEIGER COUNTER: Using a Geiger Muller counter, this radiation monitor can be used to detect the strength of ionizing radiation (β, gamma, X rays). 4、REAL TIME DISPLAY: Dose rate displayed per second, protective alarm response less than 5 seconds, ensuring accurate and reliable results. 5、WIDE USAGE: Widely used in environments with ionizing radiation, such as home decoration, geological survey, iron, testing vehicles, nuclear power plants, industry, radiology, radiology laboratories.
