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 for use. LCD Display with Backlight: This nuclear radiation detector features a LCD display screen that allows you to read the detection data clearly and , so you can 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 for measuring small changes in radiation levels, and has a high sensitivity for 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.
