Feature:1. FAST AND WIDE: The radiation dose alarm instrument has a high sensitivity Geiger technology tube as a detector, which is mainly used to monitor X, and hard radiation in various radioactive workplaces, with quickly response and wide measurement range2. POWER OFF MEMORY: The geiger counter display the current and cumulative dose rates in the workplace, and the calendar, time and accumulated data are stored permanently when the battery is changed3. WIDE APPLICATION: Nuclear radiation detector is widely used in nuclear power plants, accelerators, steel, chemical industry, isotope applications, industrial X gamma, radioactive stone, radioactive medical treatment, cobalt source therapy, y radiation, iodine 131, Personnel in the field of radioactive laboratories, environmental monitoring around nuclear facilities, etc., shall conduct people safety protection monitoring and radioactive warning4. MEASUREMENT DISPLAY: The radioactive dosimeter dose rate is displayed every second, and the protective alarm response is less than 5 seconds5. SCRATCH RESISTANT ABS: Digital radioactive tester adopt excellent ABS material, possess impact resistance, scratch resistance, environmentally friendlySpecification:Item Type: Nuclear Radiation DetectorMaterial: ABSBattery: 2 x AA battery(not included)Detection Rays: X, gamma, and beta raysDetector: Energy compensation Geiger counter tube low energy response is improvedDose Equivalent Rate: 0.01~100Sv/hAlarm Threshold: Dose Rate: Optionally selected in 0.05Sv/h increments within 100.0Sv/hMeasurements Display: The dose rate is displayed per second and the protective alarm response is less than 5 seconds.Package List:1 x Nuclear Radiation Detector1 x User Manual
