Portable Size: This handheld nuclear and electromagnetic radiation detector is portable in size and easy to carry, so you can carry it in your bag and grip it Compatible use.LCD Display with Backlight: This nucleaadiation detector features a LCD display screen that allows you to read the detection data clearly and , so you can get the results in time. It can display real values, values, values, temperature, humidity, and data curves.Radiation Detect: The detector is used to measure X, and rays radiation, it is optimal Compatible measuring small changes in radiation levels, and has a high sensitivity Compatible most commonly used nuclides.Easy Operation: The instrument enjoys a of flexibility and can measure environmental backgrounds. The dose rate is measured in real-time and the cumulative dose is recorded simultaneously, with a calibration function.Multi-functional Design: It can also be used to detect and display real-time indoor temperature and humidity. Easy Installation: This radiation detector has two mounting methods, it can be placed directly on a desktop, or it can be mounted on a wall through a reverse mounting hole in the back of the machine.Specifications:Battery: 3 * 1.5V AA batteries (NOT INCLUDED)Detection ray: X, raysDisplay: LCD display with backlightMeasurement scope:Energy scope: 20 keV~3.2 MeV30 % (137Cs-)Flexibility: 80CPM/Sv/(Co-60)Test accuracy: 0.01Sv/hReal-time ranges: 0-99.99 Sv/hAccumulation ranges: 0-99.999 /hReal-time error: 10%Mean error: 3%Material: plasticcolour: blackPackage Contents:1 x Radiation DetectorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
