[Accurate Measurement] Weight: 0.3kg. Built-in electromagnetic wave sensor processes data with a microchip and displays the numerical value on the LCD screen. Selectively measures magnetic field radiation in units of mG/μT, electric fields in units of V/m, and radiation fields in units of mW/m2. Note: The optimal measurement distance is within 0-60cm from the object being measured. Measurements beyond this range are possible, but data may be inaccurate.

[Sound and Screen Alarm] When the measured value exceeds the set value (0.4μT (4mG), 40V/m, 1mW/m2), the buzzer will sound continuously. If using in a crowded place, you can turn off the buzzer to avoid disturbing others.

[Usage Scenarios] The RF function can detect 5G signals and radio waves up to 10Ghz. The EF and MF functions can measure electromagnetic waves emitted from home appliances such as TVs, IH cooktops, rice cookers, refrigerators, computers, and electrical wiring. Note: The sensor for RF measurement is on the right side of the main unit, and the sensors for EF/MF measurement are on the top. Covering them with your hand or other objects will affect the measurement results, so please avoid doing so.

[Multi-function] Average or peak (maximum) value readings and data hold are very convenient for recording and checking. Short-pressing the GRAPH button allows you to switch the LCD screen between white and black backgrounds. Long-pressing the GRAPH button switches between two display modes, allowing you to grasp changes in numerical values. The device automatically turns off after 15 minutes of inactivity.
