An EMF meter is a handheld device used to measure electromagnetic fields, including AC magnetic fields, electric fields, and radio frequency (RF) signals. Leading models such as the Safe and Sound EM2 (about $399) and EM3 (about $649) help detect radiation sources in homes, offices, and industrial settings.

Popular EMF Meter Options (2026)

• Safe and Sound EM2 ($399): An easy-to-use, highly rated meter that measures AC magnetic and AC electric fields. It also includes a frequency-weighted mode designed to reflect how these fields may affect the human body.
• Safe and Sound EM3 ($649): A professional-grade EMF meter that measures magnetic fields, electric fields, and body voltage. Its 3-axis sensors provide accurate 3D readings, and its performance is supported by third-party testing.
• Safe and Sound Pro II ($399): A professional RF meter built for precise radio frequency measurements. It offers high sensor accuracy, third-party test verification, and is widely recognized as a leading RF meter.

Key Features to Look For

• Detection Type: Choose a 3-axis (tri-axial) meter for faster, more accurate readings without having to rotate the device in multiple directions.
• Range: Make sure the meter can measure the EMF types you need, such as AC magnetic fields, AC electric fields, and radio frequency (RF) signals from sources like smart meters and cell towers.
• Frequency Range: If needed, confirm that the device supports modern 5G frequencies, typically listed as 200 MHz to 8 GHz or higher.
• Safety Alarm: Audible alerts or color-coded displays (green, yellow, and red) make it easier to spot when field levels rise above safe limits.

Common Uses

• Measuring emissions from smart meters, Wi-Fi routers, and mobile phones.
• Finding hidden electrical wiring behind walls.
• Testing appliances such as microwaves, refrigerators, and televisions.
• Identifying high-EMF areas in bedrooms or offices to help reduce exposure.
