Why it’s different
Unlike generic RF meters, the Safe and Sound Classic III is built specifically for health-based assessment, not just engineering data. It aligns with Building Biology precautionary guidelines, helping you interpret results through colour-coded LED indicators and an audio signal that identifies the type of wireless source.
