Electrosmog meters measure the intensity of wireless radiation. These are electromagnetic fields that generate radio-frequency and microwave radiation broadcasted by cell phones, Wi-Fi, GPS, smart meters, satellite Internet and blue-tooth wearables like earbuds and watches.

Dirty electricity is most efficiently measured by an EMI or Dirty Electricity meter, which is designed to detect and monitor the potentially harmful voltage spikes and surges that radiate from the circuits and wiring of most buildings in the US.

Two leading EMI/ Dirty Electricity meters are the Greenwave Broadband EMI Meter and the Stetzerizer Microsurge Meter. These meters are easy to use. Simply plug them into electrical outlets to find out how much dirty electricity is present on nearby wiring. These meters are also very useful for guiding the installation of dirty electricity filters for optimal results. They can help you determine the best number of filters to install in each room and which combination of electrical outlets to choose for installation. (MORE)

While Dirty Electricity and wireless radiation are the most common forms of EMF pollution found in homes and businesses today, electric fields generated from electrical wiring, and magnetic fields also create electromagnetic fields (EMF). These other types of EMF pollution are typically measured with specialized meters like Gauss meter or AC electrical field meter.

It is important that you understand exactly what type (or types) of EMF your electrosmog meter is designed to measure. There are meters for each type of EMF.

One final approach to measuring dirty electricity is with an oscilloscope, or spectrum analyzer. These are expensive and more advanced measurement tools that require significant expertise and experience to use effectively.

The easiest and most cost-effective way to measure dirty electricity on building circuits is to use a plug-in EMI (electromagnetic interference) meter. The table below provides some basic information about the Greenwave and Stetzerizer meters.
