This product is a high sensitivity radiation dose alarm device, mainly used to monitor X, γ and β rays.It has features such as high sensitivity and precise measurement. Widely applied in the environment where the existing radiation environment, the human body has accepted the supervision and protection of radiation doses, such as family decoration, radiant radiation production enterprises, hygiene, radiation treatments, nuclear laboratory, nuclear station, inspectioncommercial import and export, construction materials, petroleum chemistry, general geological investigation, used steels, detection of industrial defects and others. Features: It is made of premium material, design covered with silicone, anti-slip and anti-fall, wear-resistant and with a comfortable grip.It adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation. Configured color LCD screen with multifunctional monitoring pages, real-time display of the real-time value of the current dose rate, the cumulative measured value, the cumulative stored dose flow, the maximum value, the average value, the start date, the cumulative time.The detector is used to measure X-, γ- and β-ray radiation, it is optimal for measuring small changes in radiation levels and has a high sensitivity for the most commonly used nuclides. Three alarm mode design, with sound/light/vibration alarm when the dose rate and cumulative dose exceed the threshold, and the dose rate and cumulative dose thresholds can be set manually.Wide applications, suitable for family decoration, radiant production enterprises, hygiene, radiation treatment, nuclear laboratory, nuclear station, import and export commercial inspection, building materials, petroleum chemistry, general investigation in geology, scrap steel, detectionindustrial defects and others..
