If you are walking around your home in areas, not near electronics like your television or your computer, you’ll likely get readings somewhere between 1 – 5 V/m. Now, there are cheaper meters on the market, in fact one that I absolutely love is the Meterk ( see my review), however if you’re looking for an absolute quality EMF meter, that is simple to use and provides all the information you could ever need, the Trifield TF2 is my top recommendation. I don’t want to go into detail about this subject in this guide, but I’ll point you to the following articles:

At least five new cell tower studies are reporting bioeffects in the range of 0.003 to 0.05 μW/cm2 at lower levels than reported in 2007 (0.05 to 0.1 uW/cm2 was the range below which, in 2007, effects were not observed). Researchers report headaches, concentration difficulties and behavioral problems in children and adolescents; and sleep disturbances, headaches and concentration problems in adults. Public safety standards are 1,000 – 10,000 or more times higher than levels now commonly reported in mobile phone base station studies to cause bioeffects.” This article needs additional citations for verification.

Based on my own understanding and research,It seems that the general consensus (especially in Europe) is that living spaces should be under 10 V/m at ambient levels. Anything above this is not certainly an immediate concern, but you should use your EMF meter to locate where the higher levels are coming from so you can resolve the exposure. Here's a look at five key features that set the Trifield Meter apart from other EMF meters: 1. Tri-Mode FunctionalityFrequency weighting means the meter is more sensitive to frequencies that have a greater impact on our bodies. The meter uses a weighted method that's designed to align with how these fields affect our bodies. This is based on established guidelines for human exposure to magnetic fields. Note: the manufacturer says to give the meter approximately 1.5 seconds when you turn it on, or switch modes, for the displayed reading to stabilize a bit. The Occupational/Controlled portion is in relation to a job where your exposures may be higher, but that is by choice and can be controlled. The General Uncontrolled portion are maximum levels for the general public. You can see that for the “Partial-body” portion, it must be under 1.6 W/kg, which is why cell phone manufacturers must meet this standard. If used solely in the detection of RF sources, the TF2 will likely be sufficient for most of your uses. Detection of hidden RF cameras in your hotel or vacation rental, for example.

The energy an object can radiate is measured on the electromagnetic spectrum, with the low frequencies being a low-risk and high frequencies being extremely harmful. Objects with low frequencies are things like power lines, your phone, and your microwave. High-frequency objects would be things like actual radioactive (toxic) waste, x-rays, and UV radiation (like a tanning booth). The Trifield 100XE EMF Meter also detects electric fields, which often exist independently from magnetic fields but can be just as dangerous. Ready my guide on Dirty Electricity to find out how these electric fields come about, and why they can be so dangerous. No RF Reading – The biggest downfall of the Meterk is that it only reads magnetic and electric field radiation, not radiofrequency radiation. However, this does mean that the Meterk could be a really good compliment to the Acoustimeter, which reads RF, but not electric or magnetic radiation. After looking at all of these studies and working extensively to develop the report, they came to the conclusion that 1 mG the upper limit of what you should allow your body to be exposed to.

Not Tri-Axis – Whereas many of the EMF meters on this list have tri-axis capability (meaning they will get an accurate reading regardless of orientation), the Meterk requires that the sensor (located on the right-hand side) is pointed towards the source of the radiation to obtain an accurate reading. Size – Next, the device is relatively bulky. I’m hoping that future models are designed a little bit slimmer and sleeker. The TF2 is a 3-axis gaussmeter, which conveniently allows you to take comprehensive readings from any angle. A professional meter, like the Gigahertz NFA1000 will provide sensitivity of .01 mG.

Severe Concern– Values in this category are not acceptable from a building biology point of view, they call for action. Remediation should be carried out soon. In addition to numerous case histories, scientific studies indicate biological effects and health problems within this reference range. One of my favorite features other then the flashlight is the display light on the antenna, which actually acts as an alarm. It will be green if it’s detecting less than 4 mG of radiation, yellow if it’s detecting between 4-40 mG, and red if it’s reading more then 40 mG.Quality – Latnex, although they make a variety of EMF meters including ones that measure magnetic field radiation, it has not been around as long as some of the other companies. This makes me doubt the reliability a little bit since it has not stood the test of time. Final Thoughts Brand new LCD display offers much more information than the 100XE was able to, making testing a breeze. The difference between ideal dipole radiation pattern and real probe pattern is called isotropic deviation.
