Factors to consider when choosing the best EMF meters
There are several factors you should consider when choosing the best EMF meters. These include:
If the EMF meter provides inaccurate data, it will be of no good. If you want to nail down the EMF radiation source, you should ensure that you get an accurate meter. Luckily, the EMF testers we have reviewed above have an above-average accuracy level.
Ease of Use
A good EMF detector should provide you with easy to understand readings. Consider how complicated the equipment is, how difficult it is to take the readings, and how practical it is to use this information. Consider if it’s possible to transfer the information from the device to your computer. Does the device come with a digital or analog display? All these are key considerations when choosing the best EMF tester.
Construction and design
You will want to consider the material used to make the EMF meter. Is it durable and sturdily made? When it comes to the design, EMF meters can be categorized into two: The single-axis meters and the 3 axis meters. While the single-axis meters are cheaper, they are slower than the 3 axis meters. In other words, they aren’t as good as the 3 axis meters. On the other hand, the 3 axis meters offer an extensive range and, therefore, provide more accurate results as compared to the single-axis meters.
Consider also the additional features that the best EMF detectors come with. These specs will help to improve performance and, therefore, ensure that you have precise results. For instance, if it comes with a colored LCD screen, you can easily spot the potential risk.
When trying to track down your source of EMF radiation, one of the key factors you should consider is the sensitivity in and out of your home. A cheap and insensitive EMF meter will not even trace an EMF leak to your microwave oven. A good EMF meter should pick weak signals too and not only the strong ones. This is why you need to pick an EMF tester with high sensitivity.
Your measuring needs
No one meter is a one size need for all measurements. For the best results, you need to ensure that you understand what you are measuring. Is your goal to measure magnetic fields that come from power lines, cars, and appliances? Do you intend to measure electric fields such as extension cords, lighting, and monitor? Do you want to measure the radio waves coming from microwaves, cell towers, or Wi-Fi connections? Different EMF detectors and meters are made for different needs. (we have written extensively for the best generators brands)
The wireless signals are usually transmitted across different frequency ranges. Some of the latest technologies such as 5G cellular have a very high-frequency range. If you will detect such signals, you need to pick an EMF meter that has a wide frequency range.
Just like any other device, you will want to consider how portable the EMF meter is. You want a meter that you can carry with you when traveling. Therefore, choose a lightweight meter that is also portable and easy to store.(we have written extensively for the best generators brands)
If you choose a battery-operated EMF meter, you want to ensure that it is easy to turn on and off. It should also come with a low battery indicator that shows you when the battery is down.
FAQs on the best EMF meters
What do the EMF readings mean?
EMFs are measured in a unit known as volts per meter (V/M). The higher this number is, the stronger the EMF produced by your electrical. To be safe, it’s advisable to ensure that the EMF falls within the ICNIRP’s guidelines.
According to these guidelines, the natural electromagnetic fields, such as those from the sun should be 200 V/M. The limits for power mains that are a distance from the power lines is 100 v/m. If the power mains are close to the power lines, the limits should be 10,000 v/m. The maximum for microwave ovens is 14 v/m.
How can you neutralize EMF radiation?
There are several measures you can use to end the EMF radiations. These include:
- Buy a cellphone case that can protect you from EMF radiation
- Ensure that your body doesn’t get into contact with a computer or cellphone
- Get rid of smart meters
- Get grounded
- Use healing crystals
- Spend more time in nature
Does the EMF radiation go through a wall?
Like it’s the case with electric fields, the magnetic fields are usually stronger at their source. Their strength decreases with distance. However, magnetic fields can’t be blocked by materials such as walls.
Can a phone be used as an EMF meter?
Smartphone apps can only detect EMF coming from communication equipment like Bluetooth, 2G, 3G, 4G technologies. They cannot detect other EMF sources.
How does An EMF detector work?
An EMF detector works by detecting the fields that are emitted by electrically charged objects.
What materials can I use to block EMF?
Materials such as copper, aluminum, and Mylar can attenuate EMF radiation as they scatter or absorb the photos when they pass through them.
Why do readings from different Meters differ?
Two different meters can give different results for several reasons. In a real-life situation, you will rarely find a single signal. That means you will be exposed to a mixture of signals from different sources. The frequencies, orientations, and digital characteristics of these signals will be different. The readouts will depend on how a meter interprets these signals.
What units should I Use to measure radio frequency?
When measuring RF, different units can be used. When measuring low levels of RF radiation, it’s advisable to use small units like V/M. If, on the other hand, there are huge amounts of radiation, you can consider using bigger units like mW/cm2.
What distance from the source is a meter effective?
All EMF detectors have a zero feet range. Therefore, all-electric field meters, gauss meters, and R/F microwave meters can only measure the field’s strength at the place where the meter is located. However, the effectiveness of the meter will depend on sensitivity. For instance, if a gauss meter has a sensitivity of 0.1 mG, it will be more effective than another one which can only detect a minimum of 1.3 mG. A more sensitive meter can be effectively used far away from the field source but it will still measure the field at the meter’s location.
Scientists suggest that there is a weak connection between the low –level EMF exposure and health challenges such as cancer. On top of this, high-level exposure to EMF can cause various physiological and neurological issues such as disruption of the human nerve function.
You don’t have to be afraid to use a cellphone, microwave, or Wi-fi as low exposure to EMF isn’t harmful. But the risk of high-frequency exposure is high and you need to be aware of its existence. Instead of worrying about exposure, you need to be aware of it and reduce your exposure.
One of the first steps towards reducing your exposure is by getting yourself an EMF reader. You will want to ensure that you choose an option that is accurate and will meet your needs.
Fortunately, we have narrowed down your option to the best 5 EMF testers available. With one of the above options, you can pin down your source of EMF.
This EMF meter works great and will show you a fairly safe distance to stand from the radiation source to keep you safe. Its biggest downside is that it has no RF detector. But all in all, it’s a great EMF meter that is worth buying.
