[3-in-1 EMF Meter] This 3-in-1 multifunction EMF meter is specially designed to detect the strength of radio frequency (RF), electric field (EF), and magnetic field (MF). Featuring a built-in high-precision electromagnetic radiation sensor and micro-control chip processor, it can quickly and accurately measure electromagnetic radiation levels. Whether at home or in the office, this EMF detector is an ideal tool for EMF detection.[Multifunctional Applications] The RF mode can detect WiFi signals, 5G signals (50MHz3.5GHz), and microwave radiation from microwave ovens. The ELEC and MAG modes can measure electromagnetic radiation emitted by household appliances such as induction stoves, refrigerators, printers, computers, and power cords. This EMF meter helps optimize appliance placement to avoid high radiation environments.[Audible & Visual Alarm] The EMF meter radiation detector features a three-color backlit display (green, orange, red) and an audible alarm (can be turned off). With a clear digital readout on the large LCD screen and trend indicator, you can easily monitor current field strength data. The intensity and frequency of the audible alarm increase with higher measured values.[Convenient and Practical Functions] This electromagnetic field radiation detector includes maximum value measurement and data hold functions for easy viewing and analysis. The LCD screen displays data clearly, enhancing user experience. It also features an auto power-off function after 15 minutes of inactivity to conserve battery life. Designed with ergonomics in mind, it is comfortable to hold and easy to carry.Color: As Shown Material: Plastic Package Contents: 1 x EMF Meter Note: Light reflection and differences in display screens may cause slight variations in the color shown.
