This product is one small type high sensitivity radiation dosage alarm device, mainly used to monitor the X, and hard rays. It has the characteristics such as high sensitivity and accurate measurement. Widely applied in the environment where existing ionize radiation environment, human body accepted radiation dosage supervise and protection, such as family decoration, radiation shining manufacture enterprises, hygiene, radiation treatments, nuclear lab, nuclear station, import-and-export commerce inspection, building materials, petroleum chemical, geology general investigation, used steels, industry flaw detection and others. Features: With high detection sensitivity, especially for environmental radioactivity monitoring, traces of nuclear and electromagnetic radiation can be detected. Configured LCD color screen, real-time display of instantaneous values, average values, accumulated values, etc. And the screen brightness can be adjusted. The detector is used to measure X, and hard rays radiation, it is optimal for measuring small changes in radiation levels, and has a high sensitivity for most commonly used nuclides. The dose rate is measured in real-time and the cumulative dose is recorded at the same time and has a calibration function. With a sound alarm when dose rate and cumulative dose are over the threshold, and the thresholds of dose rate and cumulative dose can be set manually. Users can switch multiple radiation dose rate units such as Sv/h, Gy/h, mR/h, cps, and cpm. With calendar clock function, supports year-month-day date setting and hour-minute-second time setting. It comes with a plastics box for easy storage and easy carrying. Wide applications, suitable for home decoration, radiation shining manufacture enterprises, hygiene, radiation treatments, nuclear lab, nuclear station, import-and-export commerce inspection, building materials, petroleum chemical, geology general investigation, used steels, industry flaw detection, and others.
