EMF testing can include a variety of alternating or direct current magnetic or electric fields. The most common sources for high electromagnetic fields include flaws in the internal building wiring system, proximity to powerlines, transformers or appliances and stray currents on utility lines.

We measure the various EMF field ranges with an EMF tester and professional emf testing equipment and assess what type of and how much EMF radiation is present. EMF/RF can decipher and answer an EMF or RF problem or question, find a solution and create low EMF/RF environments.

EMF surveys can be conducted for:

• Real estate transactions
• Health concerns
• Low EMF building design
• Building EMF assessments
• Equipment interference issues
• Reduction methods
• Green buildings
• Long-term data logging
• Future projections

EMF assessment and documentation can be provided for:

• AC Magnetic fields
• AC Electric fields
• DC Magnetic Fields
• DC Electric fields

The level of magnetic fields can vary significantly over time. Data logging at sites allows observing field fluctuations over a period of time, identifies circuits, equipment activation and source identification. In conjunction with available current load data, extrapolation can be made on projected field levels.
