Product features: - It is small, lightweight, and easy to carry. It has a built - in high - precision chip, which is practical and reliable. - It adopts a clear large - color screen and large - color font design, easily adapting to both dim and bright environments, making it more convenient. - It can detect three parameters simultaneously: quickly detect radio frequency intensity, electric field intensity, and magnetic field intensity, display the data on the same interface, and show whether the three data exceed the standard. - It is equipped with a current radiation level classification function. Three different colors correspond to different current radiation levels, allowing for a more accurate and graphical understanding of the current environment. - It has a sound alarm function. When it detects that the data exceeds the standard, it will emit a beep sound. There is also a mute button to turn off the sound. - It has a multi - functional design with a lock - screen (data lock) function, and supports displaying the maximum and average values. - It has multi - functional applications. This product can be widely used in kitchens, high - voltage equipment areas, homes, offices, factories, etc.
