At NextDay Inspect®, we offer electromagnetic field testing or EMF for short. EMF looks for exposure to high and low electromagnetic fields. The most common sources for high electromagnetic fields include proximity to power lines, transformers or appliances, and flaws in the internal building’s wiring system and stray currents on utility pipes. Exposure to high levels of EMF can cause serious health issues. We use the latest technology to help you detect where there are high levels of EMF in your house.
