[3-in-1 EMF Meter] 3 in 1 multifunction EMF meter is specially designed for detecting the strength of radio frequency (RF), electric field (EF), and magnetic field (MF). Built-in high-precision electromagnetic radiation sensor and micro-control chip processor 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] RF mode can detect WiFi signals, 5G signals (50MHz–3.5GHz), and microwave radiation from microwave ovens. 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 assess appliance placement to reduce exposure to elevated radiation levels. [ble & Visual Alarm] The EMF meter radiation detector features a three-color backlit display (green, orange, red) and an ble alarm that can be turned off. With a clear digital readout on the large LCD screen and trend indicator, users can easily monitor current field strength data. The intensity and frequency of the ble alarm increase with higher measured values. [Convenient and Practical Functions] The 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 has 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.
