Safe and Sound EM3 - 3D Magnetic Field, 1D Electric Field, Body Voltage Meter
Safe Living Technologies' new Safe and Sound EM3 Pro is North America’s first-ever, 3 in 1 pro-consumer-level, professionally accurate and affordable EMF meter.
The EM3 was optimized to measure low level AC Electric and AC Magnetic fields. The device not only meets the rigorous Building Biology guidelines SBM-2015 and SBM-2024 for electromagnetic sensitivity but also serves as a versatile tool for general electromagnetic monitoring, making it suitable for various applications in assessing and ensuring building health and safety. It is capable detecting fields as low as 0.01 V/m and 0.01 mG (1 nT). See third party calibrated specifications and frequency response plots for more details.

Safe and Sound EM3 Meter
After performing extensive Beta testing on the EM3 meter I am happy to say I am impressed with the versatility and accuracy of the meter. For both the novice, or experienced BBEC / EMRS this meter will provide valuable service as their primary source of measurement, as well as a backup testing device for those with NFA 1000's. When doing professional evaluations, having an accurate backup meter capable of reliably measuring EMF's is critical. For those new to measuring EMF’s it is wise to have a meter that provides multiple EMF testing functions that you can rely upon for accurate measurements to guide your mitigation efforts – this meter provides that capability.
