This radiation detector adopts a high sensitive Geiger counting pipes, it is mainly responsible for monitoring the radiation of X, rays in various radioactive work areas; it is featured as swift response and broad measurement scope, it is able to display the dosage equivalent rate in the work area; it is widely applied in the individual safety protections monitor and radioactive indication for work personnel in the following fields: nuclear power plant, accelerator, iron & steel industry, chemical industry, isotope application, radioactive laboratory and surrounding environment monitor of nuclear facilities. Features: 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 easily grip it for use. Large LCD Display with Backlight: This nuclear radiation detector features a large LCD display screen that allows you to read the detection data clearly and easily, so you can get the results in time. It can display real values, AVG values, ACC 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 high degree 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. Wide Applications: This radiation tester can be widely used in nuclear power plants, accelerators, the iron & steel industry, the chemical industry, isotope applications, radiology laboratories and ambient monitoring of nuclear facilities.
