electric and magnetic fields (EMFs) may cause cancer, according to the World Health Organization. How significant of a risk are you facing at home and work? An EMF meter can help you find out. EMF meters detect and measure radiation produced by cellular phones, Wi-Fi routers, computers, televisions, microwave ovens, smart meters, and other electronic devices.

An EMF meter is a handy tool

For detecting electromagnetic fields and the radiation that emits from such devices. Use an EMF meter to find the level of non-ionizing radiation coming from your cell phone. For protection get an EMF protective case to use. Having said that this is not the only place to use an EMF meter.

Using EMF meters to look for EMF radiation in the home and office is more common, especially now, because of how technology has advanced. Faster internet speeds call for an increased amount of RF radiation or radiofrequency radiation, and faster networking becomes, the more radiation becomes present around the people who use it.

Compared to the past, there is quite a bit of testing now, Which further displays the negative health effects of EMF radiation. Although at one point, most EMF meters were a tool used by ghost hunters and paranormal investigators, it would be a good idea to buy one for yourself.

When you use an EMF meter to read the level of electric or magnetic energy inside a house, it gives you an understanding of how many protective measures you should take from here on out. Most often, people who are unaware of the amount of electromagnetic field radiation they have in their home may begin to have migraines and other mild EMF sensitivity symptoms, especially if they utilize multiple 4G, 5G, and wired devices daily.

The Different Types of EMF Meters

The type of EMF meters you use depends on how, where, and why you want to test the EMF radiation. Is it for your cell phone, Wi-Fi router, desktop computer, or another device?

If you want to measure your yard’s powerlines or around wired devices inside the house, use a Gauss meter. Otherwise, you may need a radio frequency meter, which is best for measuring EMF radiation of cell phones.

There are varying frequency wavelengths for different types of devices. Do as much research as you can before choosing which type.

Gauss Meters

Gauss meters detect the magnetic intensity of an object. You would use a gauss meter to find electromagnetic wave measurements in either Gauss (G), milligauss (mG), milliTesla (mT), or microTesla (µT).

A Gauss meter is the type of meter you will want to test the electromagnetic fields around wires, powerlines, and general ambient magnetic fields in your house. Powerlines are typically a massive producer of EMF radiation, and even if they are in the furthest corner of your backyard, the electromagnetic field they create can reach all the way inside your house. Also, the amount of EMF radiation caused by nearby powerlines can depend on whether or not they are underground and how big they are.

According to the EPA, “exposure levels to EMFs around the home are in the range of 0.01–0.25 microTesla (µT) or 0.1–2.5 milligauss (mG). For homes near powerlines, these levels may be as high as 0.5–1 µT (5–10 mG).” Each country has different guidelines on this level of exposure, but of course, less radiation is best.

Radio Frequency Meter

Cell phones and Bluetooth devices have a higher frequency of EMF radiation than wired devices. That is why they call this type of EMF radiation RF because devices with this degree of radiation are in their own category on the electromagnetic spectrum.

A Radio Frequency Meter is the best type for measuring RF radiation of Wi-Fi routers, Bluetooth devices, and cell phones. Radiofrequency (RF) is actually a type of EMF radiation, but not all EMF meters measure RF specifically, so you will have to find one that does.


What to Look for in an EMF Meter

You can find high-quality EMF meters through the better, more professional brands of meters. Some EMF meters are super cheap and get the job done, but they either do not last long at all, or they lose accuracy over time. Your best bet is to stick with a trusted brand (like Latnex) and avoid budget cuts.

Not sure of a brand? Stick to these three factors to determine the best meter out of your selected choices. They all seem to be the same until you get a closer look at the capabilities.

#1: Accuracy

The accuracy of a meter is not always apparent when purchasing online. The company may provide test videos, and you can read all the customer reviews, but you might not fully understand how well the meter works until it is in your hand and ready to take a measurement.

However, a good indicator of a good EMF meter is very few complaints regarding calibration.

#2: Multiple Units of Measurement

What units does the EMF meter measure in? Does it read AC and DC power? This all depends on which type of meter you are buying, but the more units, the better because you will obtain a superior analysis of the Electromagnetic radiation.

#3: High Sensitivity

The best EMF meters can pick up even the faintest hints of EMF radiation. Look at how many decimal places the EMF meter uses to the right side of the zero. More decimal places mean that the meter can pick up more accurate and finite readings. Some EMF meters are more general and only show one decimal place – for example, 00.0

How to Choose the Best One

Some of the best EMF meters are right here in this very article. However, there are hundreds of choices. Use the three key points we talked about when looking around – accuracy, units, and sensitivity – and you will be on your way to detecting EMF radiation.

Find out what unit of measurement you need and use it as your primary guide to which meter to buy, and then eliminate options based on quality. After that, you can factor in preferences to find the perfect meter.

The more expensive EMF meters come with more options and features, but there are several entry-level, mid-market, and top market price points. Here are introductions to six EMF meters options.

Sorting out the Alphabet Soup of Radiation

The two EMFs are the Extremely Low Frequency (ELF) EMFs emitted by electricity at 60Hz. The more powerful Radiofrequency (RF) EMFs are commonly emitted by cellular phones and internet devices at much higher frequencies.  What’s the difference?

Key Differences Between ELF and RF Electric and Magnetic Fields
Mostly produced by electricity sourcesMostly produced by telecommunications technology
Produce electric and magnetic fields separatelyProduce combined electric and magnetic fields
Create currents in the body, but not heatCan cause heating in the body

Some EMF meters measure just ELF or RF radiation, and some only measure particular frequencies. The best EMF meters measure both ELF and RF-EMF radiation. What are some of the best EMF meters available? Read these brief reviews to find the best fit for you and your budget. Then check out the chart setting out the essential features of six options at every price point each.

KKMoon EMF Meter

The KKMoon EMF Meter is one of the best options at an entry-level budget price of approximately $20. With a detection range of 5Hz to 3,500MHz, the KKMoon detects ELF and most RF frequencies. The KKMoon features a sound/light alarm that automatically alerts when safe limits are exceeded. Its display features a large, clear LCD and is easily operated with just one hand. Its biggest advantage? The moon’s price. Its weak point? Diminished accuracy at lower frequencies. The KKMoon EMF meter rates are the best at the entry-level budget point. It can be purchased on Amazon here.
