Top Electromagnetic Field (EMF) Detectors for 2020

Introduction: 

EMF detectors measure fields produced by alternating current i.e. electric and magnetic fields along with RF (radiofrequency) radiation. It does so with the help of particular sensors. Each sensor is used to detect and measure each particular field. The more sensitive a certain sensor is, the more accurate it will be.   

Top EMF Detectors 2020:

  • Trifield – EMF Meter Model TF2

The Trifield TF2 can measure all three types of EMF radiation i.e. magnetic, electric, and RF radiation, so it’s no surprise that it tops our list. It gives readings quicker than most meter models and more precise readings as well. The model uses a 3-axis sensor for its ‘Magnetic’ settings which allows for more accurate readings regardless of the direction you point it in. The new design also allows for the measurement of EMF radiation within the human body via its frequency weighted mode.  In its magnetic mode it can give readings in the frequency range of 40 Hz – 100 kHz, in the electric mode it gives readings of around 40 Hz – 100 kHz and in the RF radiation mode around 20 MHz – 6 GHz.

The model comes with an LCD display and a backlight to help see readings more clearly. It not only provides more information than most EMF readers but also displays it in a simplified, easy-to-read form which makes it incredibly user friendly and ideal for beginners and professionals alike.  Another great addition to this model is the audio feature. With the audio output, you can easily locate sources of radiation around your home.

If we talk about the battery, the model still outshines, it comes with a 9V alkaline battery providing you with around 20 hours of power with the backlight turned off.  

  • GQ EMF-390/RF Meter

This EMF reader has really grown in popularity this year, it’s even listed as one of the best-selling EMF meters on Amazon. Like the Trifield TF2, this EMF meter also measures the three types of EMFs: magnetic, electric, and RF radiation.

This reader can display a large amount of information at a time, for all three types of readings. It might seem confusing or hard to decipher for beginners but more experienced users love this. You can also switch to the classic mode which will display only one type of reading at a time. As for data displayed, you can also track multiple RF radiation sources at a time, or if you like graphs, switch to the graphic function to view real-time data readings with a graph displayed of the data collected over the last 45 seconds.

What’s interesting is its ability to store all the data into a built-in flash memory which you can later download into your PC. The device also comes with a ‘safety suggestion’ feature which will warn you if you’re in the vicinity of harmful EMF radiations. 

  •  Acoustimeter RF-10

This has to be the top RF reader you’ll find on the market today. It is accurate, easy to use, and perfect for professionals. For starters, this is the most sensitive RF meter on the market, and you can accurately locate where your RF radiation is coming from by simply moving the Acoustimeter around. If we talk about frequency, the Acoustimeter can read up to 8 GHz, a far wider range than the Trifield TF2.

This device, as we mentioned before, provides ease of use.  It comes with a simple display at the top, two rows of LED lights, and also comes with audio to help locate RF radiation sources. 

Now, while the Acoustimeter is a fantastic device, it does have its drawbacks. For one, it is quite costly (almost twice the cost of the Trifield TF2) and second, it can only measure RF readings and in order to measure other EMF readings, you’ll have to get separate devices. 

  • Meterk E2470

Now if you’re looking for a more budget-friendly option, then the Meterk E2470 is the device for you. It falls far below the pricing of other devices and it’s perfect for beginners who aren’t looking to invest too much into an EMF reader at once. You can get this device, learn how it works, and once you’re confident you can upgrade to a better device according to your needs.

The Meterk E2470 is actually pretty easy to use. It comes with a simple LCD display and a range of buttons that are easy to work with. It will also set off an alarm in case you come close to dangerous levels of EMF radiation. The screen will also turn from green to red when the readings get higher than normal. 

The only downside to this device is the lack of RF readings; it can only measure magnetic and electric radiation. All in all, it’s a great choice for the first shot at an EMF reader. 

Applications of EMF:

EMF detectors or EMF meters have a number of applications:

  • They are used to measure RF radiation (radiofrequency radiation) from mobile devices, routers, and towers. 
  • They are used to measure magnetic fields produced from AC (alternating current) passing through power lines and transformers. 
  • They are used to measure electric fields, particularly around electric devices. 
  • EMF detectors can be used to detect problems in electrical wiring and power transmission lines. 

Conclusion:

EMF sources continue to grow around us day by day especially with the rollout of 5G and more smart electronic devices. In the short term, EMF radiation does not do a lot of harm but it can get quite harmful in the long run. This is why it’s better to be aware of what levels of radiation you’re surrounding yourself with. This is where EMF readers come into the picture. They can help determine the amount of EMF in your immediate surroundings and help you take the necessary steps to reduce them.
