Safe and Sound Classic II RF Detector



Compact, simple-to-use detector for Radio Frequency (RF) / Microwave Radiation from wireless devices and infrastructure. Unlike any other detector in its price range. Able to detect frequencies between 200 MHz and  8 GHz. Sensitive below 1 µW/m2. Designed by Safe Living Technologies with electrosensitive clients in mind. Color coded LEDs identify exposure levels that correspond to Building Biology Guidelines. Requires no previous technical experience.



Safe and Sound Classic II RF Detector

Unlike any other RF detector in its price range. The Safe and Sound Classic II RF Detector is a compact, simple to use detector for Radio Frequency / Microwave Radiation. Provides a quick and simple assessment of the RF present in your environment and requires no technical experience. Uses color coded LED’s (which correlate to measurement ranges) to assess the RF exposure in your environment. The Safe and Sound Classic II also has a sound signature analysis, which helps identify the RF sources you are being exposed to. Engineered and designed by the RF Engineers of Safe Living Technologies. Manufactured in Canada. Circuit board made in Silicon Valley, USA.
