<p>[3-in-1 EMF Meter]3 In 1 multifunction EMF metre 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, micro-control chip processor can quickly and accurately measure the value of electromagnetic radiation. Whether , in the office, EMF detector is the ideal tool for EMF detection.</p> <p>[Multifunctional Applications]RF mode can detect WiFi signals, 5G signals (50MHz-3.5GHz) and microwave radiation generated by microwave oven appliances.ELEC and modes can measure electromagnetic radiation emitted by household appliances such as , electromagnetic stoves, refrigerators, printers, computers, and power cords. EMF meters helps to layout appliances to avoid you being in a high radiation environment.</p> <p>[Audible \u0026 Visual Alarm]EMF meter radiation detector has a three-colour backlit display (green, orange, red) and an audible alarm (can be turned off).With the clear digital readout on the large LCD screen and the trend , you can get a clear picture of the current field strength data. The intensity and frequency of the audible alarm will be enhanced according to the increase of the measured value.</p> <p>[Convenient and Practical Functions]Electromagnetic field radiation detector is equipped with the functions of maximum value measurement and data retention, which are convenient to view and understand strength value.LCD liquid crystal display screen, the data is clear and easy to read, which improves your using experience. And has an automatic shutdown function after 15 minutes of no operation to save energy. Ergonomic design, comfortable to hold with one hand, easy to carry.</p> <p>Colour:As Shown</p> <p>Material:Plastic</p> <p>Package Contents:</p> <p>1x EMF METER</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
