What does an EMF meter measure?

An EMF meter measures electromagnetic field emissions from sources such as power lines, household wiring, Wi-Fi routers, mobile phones, and smart meters. Different meter types cover different frequency bands: low-frequency (ELF) meters detect fields from wiring and appliances, while RF meters detect radio-frequency radiation from wireless devices.

What is RF radiation?

RF (radio frequency) radiation is a form of non-ionizing electromagnetic radiation emitted by wireless devices including mobile phones, Wi-Fi routers, Bluetooth devices, and smart meters. It operates in the frequency range of roughly 3 kHz to 300 GHz. An RF meter allows you to measure the field strength in your environment.

How do I reduce EMF exposure?

Practical steps to reduce EMF exposure include: measuring your environment with an EMF meter to identify the strongest sources; increasing distance from devices such as routers and smart meters; using shielding fabrics or paint in high-exposure areas; choosing wired connections over wireless where possible; and wearing anti-EMF clothing in situations where you carry devices close to your body.
