Radio frequency (RF) radiation and electromagnetic fields surround us at all times in varying intensity. Strong fields can be found around cell phone towers and high voltage facilities. These fields can be detrimental to electronic devices as strong electromagnetic fields can actually change electrical currents, causing some electronics to malfunction.

Another increasing issue is the concern about the negative health effects from high intensity radio frequencies or electromagnetic fields. While there is little strong evidence of this many people would rather not take the chance.

This Triple Axis EMF Tester is designed to conduct a full survey of an electromagnetic field without having to tilt and turn the sensor as is required with single axis testers. This makes for a faster and more accurate measurement of an EMF and maximizes efficiency. The 480826 EMF Tester Triple Axis User Manual is attached to this page to answer any further questions.
