It is made of high quality material, silicone coated design, non-slip and drip-proof, wear-resistant and comfortable to grip. Uses a high-quality counter tube with high detection sensitivity, especially for monitoring environmental radioactivity to detect traces of core radiation and electromagnetic radiation. Configured LCD colour screen, with multifunctional monitoring pages, real-time display of current dosage performance, real-time value, cumulated measured value, accumulated saved dosage power, maximum value, average, start date, cumulated time. The detector is used to measure X-ray, GA, and radiation, it is ideal for measuring small changes in radiation levels and has a high sensitivity to the most commonly used nuclids. Three alarm modes with sound/light/vibration alarm when the dose rate and cumulative dose are above the threshold, and the dosage rate thresholds and cumulative dose can be set manually. This product is a highly sensitive radiation dose alarm device, which is mainly used to monitor the X-ray, It and B. It has features such as high sensitivity and accurate measurement. Widely used in the environment where the existing radiation environment, the human body monitors and protects the radiation dose, such as petroleum chemicals, general examination of geology, used steels, detection of industrial defects and others. Features: The detector is used to measure X-ray, It is ideal for measuring small changes in radiation levels and has a high sensitivity for the most commonly used nuclides. Three alarm modes with sound/light/vibration alarm when the dose rate and cumulative dose are above the threshold, and the thresholds for the dose rate and cumulative dose can be set manually. Wide applications, suitable for family decoration, radiant gloss production companies, hygiene, radiation treatments, nuclear laboratory, nuclear power plant, import and export trade inspection, building materials, petroleum chemicals, general geological examinations, used steels, industry Streieerrordetection and others.
