3rd Party Certified RF Detector with full frequency response from 700MHz to 9GHz 

The first of its kind, the Safe and Sound Micro RF Detector is wearable wristband detector. An innovative product of our own design and engineering, this device will notify you with a small vibration when environmental wireless radiation exceeds your desired exposure level. Moreover, with a push of a button, a color-coded light display will indicate the intensity of surrounding exposure.

Allows for 24/7 monitoring of your environment 


  • Wristwatch style design. Wristband is black and made of Silicon.  
  • Alarm function can be set to eight different vibration thresholds. It can also be adjusted to four different vibrational amplitudes.
  • LED color-coded light display identifies eight exposure levels

     red fastest blink      = >1,000,000 µW/m²

     red fast blink          = 100,000–1,000,000 µW/m²

     red slow blink         = 10,000–100,000 µW/m²

     red                          = 1,000–10,000 µW/m²

     orange                    = 100–1,000 µW/m²

    yellow                     = 10–100 µW/m²

     green                     = 1–10 µW/m²

    green blink             =  <1 µW/m²

Allows for 24/7 monitoring of your environment, Safe and Sound Micro RF Detector is small, compact, durable and discreet. Super sensitive detection, designed with the electro-hypersensitive person in mind. Accuracy fully certified, operates on a rechargeable battery. Easy to use and understand; no technical experience required.

    Safe and Sound products are my favourites

    Posted by Gregory F. on 18th Mar 2022

    My wife suffers from EMF. For 3 years, I stopped using radiation and I use meters to control the amount of pollution I receive while doing my work activities. I ask all customers to switch to airplane mode and turn of Wi-Fi and Bluetooth. I own a Safe & Sound Pro 2 which I find fantastic. I tested other brands, but I prefer this device. I much appreciate the LEDs, the screen, the solidity, the size, the easiness of use, and the fact I can plug the USB cable to save my rechargeable batteries. I am looking forward to test this new watch and use it in parallel with the Safe & Sound Pro 2. This Micro meter should help me to more discreetly check that my customers are not irradiating me too much. More and more people have stupid connected watches which is a pain. On the apple watch, radiation cannot even be switched off, it is scandalous. Thanks a lot to Safe Living Technologies for developing these products to help us save our health. Have a nice day and take care ! Gregory

    Micro RF Detector

    Posted by John Cameron on 15th Mar 2022

    I just received the device. I am in a bit of shock. The green light has yet to show up. Sometimes yellow, mostly orange and red. It will be interesting to see what color shows up at work tomorrow. Easy to use and understand, convenient, and portable.

    Discrete RF detector on my wrist? Game changer!!

    Posted by Etta, Burnaby, BC on 7th Mar 2022

    This device is life changing for someone who is hypersensitive to cell towers, phones, wifi, etc. I can now walk around my neighborhood and easily determine where it is safe for me. I was surprised how high the readings are while driving - I will put more thought into my driving routes. My anxiety has dropped like a rock - if it isn't safe for me to linger in a location, I now know it and can move on. The device also picked up cell phone signals flying through my front door / hallway, I had no idea this was happening. The detector is accurate and easy to use. I like the full shielding of the unit on the back. It is comfortable to wear (not too big). I wish it could also be a watch, but I have no idea if this is technically possible. Thank-you so much for bringing this device into your product line!!

    Slick, Clever, Smart, and Convenient !

    Posted by Aleister Tanek Javas Mraz on 23rd Feb 2022

    The Safe and Sound Micro RF Detector is a very effective device. Without having to get out a bulky meter, I was able to demonstrate to my carpool (while driving) the RF levels on the highway as we passed cell towers. A few days later, I went to check out a co-working space, and by setting the device's alert function I was able to assess how much RF was in the space by feeling the device vibrate on my wrist without "scaring" the hosts who showed me around. I've also visited a client who lived out of the way, who had some neighbours visiting; I was able to quickly discuss my work and show that the home had minimal RF levels very easily, and this little bit of smart credibility allowed me to hand out business cards to these potential new clients. Overall, the Safe and Sound Micro RF Detector is not only great functionally for detecting RF levels, but also works simply as an educational tool while doubly helping to provide a super light-weight and discreet means of informing oneself about exposure levels in day-to-day life. Really great, and thanks to SLT for your inventiveness !
