This product is a high sensitivity radiation dosage alarm device, mainly used to monitor the X, γ and β rays. It has the characteristics such as high sensitivity and accurate measurement. Widely applied in the environment where existing radiation environment, human body accepted radiation dosage supervise and protections, 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. It is made of premium material, silicone covered design, antislip and antidrop, wear resistance and with comfortable grip feeling Adopts a quality counting tube with high detection sensitivity, especially for environmental radioactivity monitoring to detect traces of nuclear radiation and electromagnetic radiation Configured LCD color screen, with multifunctional monitoring pages, real-time display of current dose rate real-time value, cumulative measured value, cumulative stored dose rate, maximum value, average value, starting date, cumulative time The detector is used to measure X, γ and β rays radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides Three alarm modes design, with sound/light/vibrating alarm when dose rate and cumulative dose are over threshold, and the thresholds of dose rate and cumulative dose can be set manually Wide applications, suitable for 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 Specifications: Material: ABS+silicone Display: LCD Battery: 1 * built-in 1100mAh rechargeable lithium battery Sensors: Geiger-Muller coungter tube Ray Detection: X, γ and β rays Radiation dose rate ranges: 0.01μSv/h-1000μSv/h (can be up to 10mSv/h) Item size: 120 * 78 * 27mm / 4.72 * 3.07 * 1.06in
