EMF Meter, Detects Electric and Magnetic Fields, Handheld Digital EMF Detector with LCD Display, Sound-Light Alarm, Rechargeable Battery for Home, Office, and Appliances (Blue)

Important Measurement Note：Magnetic field (MF) readings may show 0 if the tested device is not powered on or if the radiation level is below the meter’s detection range (0.1mG–999.99mG). For accurate results, ensure the appliance is switched ON and operating, and position the top sensor of the meter close to the source. Easy-to-Read LCD with Data Hold. The data hold function allows you to freeze readings for easy recording. The LCD screen ensures clear visibility, even in dark environments. The device automatically powers off after 5 minutes of inactivity to help conserve battery life. Versatile Applications for Home and Office:Suitable for detecting low-frequency EMF radiation from household appliances, including TVs, computers, microwave ovens, induction cookers, refrigerators, and power lines. It helps identify EMF sources and optimize your environment. This EMF detector is useful for home inspections, workplace safety, and even paranormal investigations. Sound and Light Alarm for High EMF Levels: When the electric field exceeds 40V/m or the magnetic field surpasses 0.4µT (4mG), the screen turns red, the indicator light flashes, and the buzzer sounds an alarm to notify you. A mute mode is available for quiet environments. PRECISE MEASUREMENT： ERICKHILL emf reader built-in electromagnetic radiation sensor displays the radiation value on the clear LCD digital display after processing by a control microchip. It can test magnetic field radiation with optional units mG/µT and the electric field with unit V/m. Electric field Range: 1V/m-1999V/m,Alarm threshold: >40V/m.Magnetic field Range:0.01μT-99.99μT / 0.1 mG - 999.99 mG,Alarm threshold: >0.4μT / 4mG. True EMF protection starts with detection. Our emf meter helps you: 1) Find dangerous radiation hotspots in your home/office, 2) Scientifically verify if EMF shielding products actually work by comparing before/after readings, and 3) Continuously monitor protected areas to ensure they stay below the 0.4μT safety standard. The smart way to shield - test first with our professional-grade detector for guaranteed results.
