Features: Stylish appearance design, anti-slip and smooth, comfortable hand feeling. Configured LCD colorful screen, you can set parameters and see the real time data clearly. Equipped with carabiner, tripod for multiple wearing styles and convenient use on working surfaces. Simultaneous measurement of cumulative dose and dose rate display, and it also will display CMP. Equipped with LED indicator light, which can reflect the intensity of rays according to the flashing frequency of the LED. Support preset dose rate and cumulative dose alarm thresholds. Sound, vibration, light, mute totally four alarm modes can be selected arbitrarily. Multifunction design, support automatically switch measurement units, store measurement data when alarming, save cumulative dose and cumulative starts date. Low power consumption design, power and battery voltage status indication, accumulated dose can be stored for a long time after power failure. With real-time clock function, the clock runs normally after shutdown. Built-in fault detection, dose rate overload alarm and multi-protections functions. Wide applications, which can be mainly used for radiation monitoring of X, gamma rays and hard beta rays , suitable for nuclear power plants, accelerators, isotope applications, industrial X, gamma non-destructive testing, radiotherapy, cobalt source therapy, gamma irradiation, radioactive laboratories, environmental monitoring around nuclear facilities and other fields. Specifications: Name: Body Dose Equivalent Detector Material: plastics Battery: 1 * AAA battery, low power consumption, background measurement can be used for 20 normal working time (not included) Measuring ranges: Dose rate: 0.01 μSv/h-150mSv/h Cumulative dose: 0.00μSv-999.9mSv Energy range: 40Kev-3.0Mev Energy response error: ≤±30% (relative to 137Cs) Relative basic error: ≤±10% Measurement time: The measurement time is automatically selected according to the ray's intensity, and the response speed is faster Alarm threshold: 0.5, 1.0, 2.5, 10, 30, 50, 100, 500 μSv/h Alarm response time: 3 seconds Display mode: graphic dot matrix LCD Display units: dose rate (μSv/h or mSv/h) and cumulative dose (μSv or mSV) - SI units Item size: 110 * 68 * 21mm / 4.33 * 2.68 * 0.83in Item weight: 70g / 2.47ounce Package size: 180 * 140 * 40mm / 7.09 * 5.51 * 1.57in Package weight: 250g / 8.82ounce Packing List: 1 * Body Dose Equivalent Detector 1 * Carabiner 1 * Tripod 1 * Guideline
