Radio-Frequency EMF Meters

Radio-frequency EMF is produced by all transmitters of radio signals. This includes transmitters outside of the home, and some inside.
Outside the home are TV station and radio antennae, mobile phone masts, and radar transmitters (at airports and some military installations), to name a few.
Inside the home are wi-fi routers and other wi-fi devices, computers, electronic pads, mobile phones, cordless devices such as phones and baby monitors, wireless burglar alarm components, wireless heating control units, microwave ovens, smart TV units and smart meters – to name a few.
Radio-frequency EMF has been associated in numerous studies with many biological effects and health issues. Most of us are exposed to ever-increasing EMF levels, so we believe that it makes a lot of sense for everyone to monitor the level of their exposure, and possibly take action to reduce it.
A good radio-frequency EMF meter thus becomes a basic necessity. With its help, most people can find various ways to reduce their exposure, and that of their family.
Don’t confuse radio-frequency EMF with low-frequency EMF. These are two entirely different kinds of radiation. Good radio-frequency EMF meters tend to be expensive, unfortunately.
The best meters are what is known as triple-axis. They measure the EMF in three different planes at the same time, and sum those components into a single measurement. It saves you having to do it manually, as you would with a single-axis meter, which just measures the radiation in one plane.
But most triple-axis meters allow you to operate the meter in one plane as well, which can be useful when you are trying to locate an EMF source. (Point the meter, and see which direction gives the highest reading.)
Some meters are more sensitive than others. A more sensitive meter will be able to detect a lower level of radiation – nice to have, but not essential if you are just trying to reduce very high EMF levels to something less extreme.
When comparing the specifications of various meters, bear in mind that they may all be using different units of measurement (e.g. mV/m or V/m or uW/m2 or mW/m2 or W/m2 or mW/cm2 or uW/cm2 or nW/cm2) Some of these units result in measurement values with lots of decimals, which may make them harder to understand.
I prefer mV/m or uW/m2. Many meters allow you to choose the measurement unit. Make sure you know what units you are using when making comparisons.
In general, radio-frequency EMF meters are somewhat harder to use than low-frequency EMF meters, and it helps if you are technically minded.
Here are some of the meters which seem to offer good features at reasonable value.
