Feature:1. High Accuracy and Sensitivity: The detector is used for measuring β γ and X ray radiation, which is most suitable for measuring small changes in radiation level, and is highly sensitive to the most commonly used nuclides.2. Rapid Response: The monitor responds quickly to radiation and gives an alarm in a high risk environment in a timely manner, which has high flexibility to measure the environmental background and update the detected values in real time.3. Intuitive Display: Geiger counter has a large color display screen, which is more intuitive and convenient when viewing data, allowing you to easily and quickly read real time values. And the buttons are easy to use.4. Portable Size: This tool is compact and very convenient for daily use, you can carry it in the tool bag without taking up too much storage space.5. Wide Application: This tester can detect electromagnetic radiation and nuclear radiation, meet the needs of family life detection, substation detection, mobile iron tower detection, etc.Specification:Item Type: Nuclear Radiation DetectorMaterial: ABSTest Type: β, γ, X rayDisplay Mode: LCD, backlitEnergy Range: 20kev-3.2mev ≤±30% (137Cs-)Sensitivity: 80cpm/μSv/(Co-60)Test Accuracy: 0.01μSv/hReal Time Range: 0-99.99μSv/hCumulative Range: 0-99.999mSv/hReal Time Error: ≤10%Mean Value Error: ≤3%Power Supply Mode: 3 x 1.5V AAA dry batteries (shipped without batteries)Battery Duration: ≥4 hoursSize: Approx. 105x70x30mm/4.1x2.8x1.2inWide Application: It can detect electromagnetic radiation and nuclear radiation, which can meet the needs of family life detection, substation detection, mobile iron tower detection, etc., can also be applied to material detection, environmental detection, radiation guard, radioactive medical screening, etc..Package List:1 x Nuclear Radiation Detector
