Safe and Sound Classic RF Detector

The Safe and Sound RF Detector is a compact, simple to use detector for Radio Frequency / Microwave Radiation. Manufactured and designed in Canada with circuit board that are made in Silicon Valley, USA. Provides a quick and simple assessment of the RF present in your environment and requires no technical experience. It uses color coded LED's which correlate to measurement ranges to assess the RF exposure in your environment. The Safe and Sound also has a sound signature analysis which helps identify which RF Sources you are being exposed to.


  • No technical experience required, easy to use and understand
  • True response detection range: 400 MHz to 7.2 GHz +/- 6dB (effective 200 MHz to 8 GHz)
  • Same measurement technology as the Safe and Sound Pro II RF Meter
  • Will measure 5G signals in the 200 MHz - 8 GHz range
  • Sound signature analysis to assist with source identification
  • Measurement ranges based on current Building Biology guidelines for sleeping areas
  • Uses state of the art measurement technology and is sensitive below 1 µW/m²
  • Color coded LED's which identify exposure levels corresponding to Building Biology Guidelines
  • EHS Friendly to hold - low emissions from electronics inside when sound is disabled
  • Battery operated (2 x AAA) - 8 to 12 hour battery life
  • Small, durable and compact handheld design - 65mm X 90mm X 21mm (2.5" X 3.5" X 0.8")
  • Engineered in Canada - Manufactured in Canada and the USA
  • 2 Year Warranty
