Home Test & Measurement EMF Meters

Why is EMF measuring equipment important?

Radiation is completely invisible. It has no smell, no taste, and is colourless, yet high exposure can nonetheless have serious effects on ones health. It is very important to be able to detect EMF levels in order to prevent the risks associated with long-term (chronic) exposure, be it in the home, at work, or elsewhere.

These measuring instruments are especially important for businesses that utilize a lot of electronic equipment; an environment with high levels of electromagnetic radiation can cause severe interference with devices like radios, televisions, cell phones, and computers. This can prevent the equipment from working properly, or even damage them beyond repair.

Is all EMF radiation the same?

No. There are three main types of electromagnetic radiation:

  1.  Low-frequency (LF) EMF: often emitted from sources such as power transformers, high voltage cables, and home appliances.
  2.  High-frequency (HF) EMF: caused by modern communication equipment like mobile phones, laptops, and WiFi routers
  3.  Natural EMF: Naturally occuring electromagnetic fields, either from a build-up of electricity in the atmosphere caused by thunderstorms, or from the Earth's natural magnetic field.

Which magnetic field analyzer should I use for a certain EMF?

These forms of EMF all run on different frequencies, and so specific equipment is required in order to detect the various types of radiation, depending on the source.

For example, to measure low-frequency magnetic fields, you might use a gauss meter such as the mg-300. On the other hand, the HF-B3G would be best for measuring high-frequency EMFs.
