This radiation survey meter can test the radiation of high-frequency intensity, electric field intensity, magnetic field intensity to reach the optimal test result. It is equipped with a built-in electromagnetic radiation sensor which can display the radiation value on LCD the digital display after processing by the control micro-chip. It has a radiation level assessment function, which can quickly detect and assess the radiation level. You can make reasonable processing or taking effective prevents measures toward the electromagnetic radiation according to the test result. If you need it, come and have a try, it will not let you down. Features: Large Color Display: Large color screen with backlight brightness adjustment function. Clear definition with large and colorful font design, real-time display test data, it can easily cope with dim and bright environments to give you a more comfortable experience.   Multi-parameter Detection: Electromagnetic radiation detector can simultaneously detect three parameters (high-frequency intensity, electric field intensity, magnetic field intensity), providing a comprehensive radiation detection, making it more practical. Radiation Level Assessment: The device has a radiation level assessment function, which can quickly detect and assess the radiation level. If the detected item exceeds the standard, the corresponding font color will turn red to remind the user. Trend Graph Function: Electromagnetic radiation detector with trend graph function, the user can intuitively view the trend of data changes, a better understanding of the changes in radiation levels. Multiple Functions and Parameter Settings: The device has lock screendata lock, battery level indication and other functions. At the same time, the system can be diversified settings, including shutdown time setting, language switching, screen brightness adjustment, button sound adjustment, sound alarm, etc., you can also manually set the alarm value of three parameters to meet the user"s individual needs. Widely Applications: This radiation tester can be widely used in the home, office, outdoors, industrial sites, radiological laboratories, and the surrounding environment; It is also suitable for televisions, refrigerators, and high-voltage line radiation detection monitors.
