YOJOCK EMF Meter,3 in 1 EMF Detector Electromagnetic Field Radiation Detector for EF,MF,RF,EMF Reader for Home EMF Inspections,Office,Outdoor,Ghost Hunting

[3-in-1 EMF Meter] This multifunctional EMF meter is specifically designed to detect Radio Frequency (RF), Electric Field (EF), and Magnetic Field (MF). Equipped with a high-precision sensor, it quickly captures and displays changes in electromagnetic fields. Due to fluctuations in the Earth's magnetic field and interference from nearby devices, electromagnetic fields may vary even in the same environment. This is a normal occurrence.
[Visual and Sound Alarms] EMF detector features a three-color backlight display (green, orange, red) and and a sound alarm that can be turned off. When magnetic fields exceed 0.4µT (4mG), electric fields go beyond 400V/m, or RF levels surpass 50mW/㎡, the screen turns red, and an audible alarm alerts you to take action. Perfect for everyday use at home or work, it helps enhance electromagnetic safety.
[EMF Detection and Protection] Aging or damaged household appliances may emit higher-than-normal electromagnetic radiation. For example, a microwave with a faulty door seal could lead to radiation leakage. High-powered appliances, industrial equipment, or living near high-voltage power lines can also increase EMF exposure. Use the EMF detector regularly to detect EMF levels, identify risks, and take action (e.g., moving devices or reducing usage time) to protect you and your family's health.
[Versatile Applications] EMF reader offers three detection modes for home and office use. RF mode detects radio frequency and microwave radiation from Wi-Fi routers (under 3.5 GHz), cell phones, and microwaves. ELEC mode measures electric fields from outlets, computers, and TVs. MAG mode detects magnetic fields from high-power devices like refrigerators, air conditioners, power cords, and transformers. Ideal for identifying potential electromagnetic risks in everyday living environments.
[Easy to Use] After powering on, press the FUNC button to switch between modes—each press cycles through one mode: RF (mW/㎡), EF (V/m), and MF (uT or mG). Choose the mode you need, then place the device near the appliance to measure electromagnetic field changes. The screen is easy to read, and even first-time users can operate it effortlessly. With an auto shut-off after 15 minutes of inactivity, it saves battery and is convenient for on-the-go detection.
