Safe Living Technologies is pleased to introduce the Safe and Sound EM2 EMF Meter. Designed to meet our professional standards of accuracy and reliability

The Safe and Sound EM2 meter is designed to measure both electric and magnetic fields, combined into a single unit. The EM2 is an AC gaussmeter, and a single-axis AC electric field meter, that combines all the features needed for fast and accurate measurements of electromagnetic fields (EMF). Includes a simple, easy to ready LED display.

Designed for ease of use, the Safe and Sound EM2 EMF Gauss Meter features a clear display and intuitive controls, making it accessible for both beginners and professionals. Its compact size allows for convenient portability, ensuring reliable measurements wherever you need them.

The EM2 is equipped with built-in rechargeable NiMH batteries designed for convenience and reliability. Once the device is powered on, you'll immediately see the current battery capacity displayed in clear increments: Full, Medium, Low, or Charge. Throughout use, the battery status icon dynamically reflects the charge level, shifting between full, medium, low, or empty as needed.

When it's time to recharge, simply connect a USB-C power cable to the Power Input connector. As soon as charging begins, a blue LED indicator beneath the USB-C port will illuminate, providing a clear visual confirmation that the EM2 is recharging. For optimal performance and battery longevity, it's recommended to allow the unit to charge for a full 12 hours. A fully charged battery battery can last with up to 24 hours of use.

Measure exposure levels

Find problem areas fast

Calibrated readings

Ideal for home surveys

See what is really happening in your space

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.

The smartest buyers do this before they spend a penny on shielding

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.

Built for home checks, office surveys and everyday practical testing

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.

Residential exposure to extremely low frequency magnetic fields (ELF MF) has been associated with childhood leukaemia relatively consistently in epidemiological studies.

We want young people and parents to be able to make better-informed choices around how they use mobile phones.

The strongest evidence for health risks is from exposure to fields generated in connection with use of electric power.

— Anders Ahlbom, Epidemiologist, Karolinska Institutet

The study did not reveal an increased risk, but one could not conclude that there was no risk because there were sufficient results suggesting a possible risk.

WHY LOWER EXPOSURE?

Understanding EMF exposure in everyday life

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.

Frequently Asked Questions

What detector is best for me?

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

What does an EMF detector actually measure?

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.

Do I need a detector before buying shielding products?

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.

What is the difference between RF, electric and magnetic fields?

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.

Are detector tools suitable for home use?

Yes. Many detector products are used by homeowners to check bedrooms, desks, living spaces, routers, appliances and other high-use areas.

Can detector tools also be used professionally?

Yes. More advanced analysers are commonly used for workplace surveys, consultant work and more detailed investigations.

Why do readings change as I move around a room?

Exposure can vary depending on distance, signal source, nearby wiring, appliances, wall placement and how the environment is set up.

Can a meter help me compare changes I make?

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.

Are all EMF meters the same?

No. They vary by sensitivity, frequency range, ease of use, speed of reading and what types of fields they are designed to detect.

What should I test first?

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.
