Terms apply. How it works
If you are concerned about EMFs, guesswork is expensive.
A detector gives you something better than opinions, assumptions or vague worry. It gives you readings. It shows you where the problem is, what changes when you move things, and whether you are dealing with wireless signals, wiring-related fields or something else entirely.
That is why so many people start here first: measure first, then make the right move.
Most people buy too early.
They assume the issue is the router. Or the phone. Or the smart meter. Or the bedroom wall. And sometimes they are right. But often they are solving the wrong problem.
A good detector helps you narrow it down. It helps you spot hotspots, compare rooms and make decisions based on what is actually there — not what you fear might be there.
That means less wasted money, less confusion, and far more confidence in what to do next.
Whether you are a homeowner, remote worker, consultant or simply trying to make better decisions around your family, a detector helps turn uncertainty into clarity.
Use it to test the places that matter most: your bed, your desk, your laptop area, your child’s room, your fuse board, your router position, your appliances, or your travel environment.
When you can see the reading, you stop guessing.
Trusted by health experts worldwide
Electromagnetic fields, or EMFs, are part of modern life and are generated by many everyday technologies. Exposure can vary depending on the type of source, how close it is to the body, and how long it is used. Some forms of EMF exposure have been classified as possible carcinogens, while researchers and health bodies continue to study long-term effects. This section helps you better understand common sources and practical ways to reduce unnecessary daily exposure.
For most people, the best detector to start with is the Safe and Sound Pro II if you want to measure wireless radiation like Wi-Fi, Bluetooth, mobile signals and smart devices. If your concern is house wiring, plug sockets or appliance-related electric and magnetic fields, a low-frequency meter such as the Safe and Sound EM3 or Gigahertz ME3030B is the better choice. For professional surveying, Gigahertz detectors are the stronger option, while MVG detectors are best suited to occupational use near antennas and high-power RF sites
Different detectors measure different things. Depending on the model, a meter may measure RF signals, electric fields, magnetic fields, dirty electricity, or a mix of these.
Not always, but measuring first is often the most practical starting point. It helps you see what type of field is present and whether shielding, grounding, relocation or another change makes more sense.
RF is typically linked to wireless signals such as phones, Wi-Fi and Bluetooth. Electric and magnetic fields are more commonly associated with wiring, appliances and power sources.
Yes. Many detector products are used by homeowners to check bedrooms, desks, living spaces, routers, appliances and other high-use areas.
Yes. More advanced analysers are commonly used for workplace surveys, consultant work and more detailed investigations.
Exposure can vary depending on distance, signal source, nearby wiring, appliances, wall placement and how the environment is set up.
Yes. One of the main benefits of a detector is checking readings before and after changing your setup, such as moving devices, turning equipment off, or adding shielding.
No. They vary by sensitivity, frequency range, ease of use, speed of reading and what types of fields they are designed to detect.
Most people start with the places they spend the most time: bed area, desk, sofa, router location, fuse board area and devices used close to the body.
