[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 (50MHz–3.5GHz), and microwave radiation from appliances such as microwave ovens. The ELEC and MAG modes measure electromagnetic radiation emitted by household devices including induction stoves, refrigerators, printers, computers, and power cords. This EMF meter helps optimize appliance placement to minimize exposure to high radiation environments.[Audible & Visual Alarm] The EMF meter radiation detector features a three-color backlit display (green, orange, red) and an audible alarm that can be turned off. With a clear digital readout on the large LCD screen and real-time trend display, users can easily monitor current field strength. 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 reading and analysis. The LCD screen provides clear, easy-to-read data, enhancing user experience. It also has an auto-shutdown function after 15 minutes of inactivity to conserve battery life. Designed with ergonomics in mind, it is comfortable to hold in one hand and convenient 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 between the color of the item in the photo and the actual product.
