The Best RF Meter

Here’s what makes the Safe and Sound Pro II RF Meter a seriously compelling device—and why if you care about Radio Frequency (RF) exposure, it might be your best investment.

It’s a professional-grade RF / microwave radiation detector designed to measure ambient RF signals (including common modern wireless sources like WiFi, cell towers, 4G/5G, smart meters, etc.) with good sensitivity and precision. With this meter, you get third‐party certification, calibration, more reliable specs.

This meter has also been selected by world-renowned environmental toxicologist Dr. Magda Havas for her Global RF Project, launched in March 2021. Please check it out; volunteers are needed for community-based research.

RF Meters – Reviews

Safe and Sound Pro II – RF Meter

“Excellent product with good battery life. I like that is receives from only one direction, that way it can be used to identify the source of radiation. The sound is also a great feature to help identify the type of radiation source (bluetooth, wifi, cellular, etc.) I have owned the meter for just a few weeks and have used it everyday so far to identify sources, implement mitigation methods, and re-test to confirm effective mitigation. Awesome tool”

Safe and Sound Micro 2.1 RF Detector

“I desperately wanted to order this but was skeptical that I really did not need it. Well the skepticism is gone as it has been so enlightening to have this meter on vibrate around other people and finding hot spots and being able to ask for cell phone etiquette (eg sitting at dinner for extended time with a cellphone hidden in a pocket I would not have known was radiating). Also, without it I would not have realized that where my dog bed was located on the floor directly above the router and needed relocation for the health of pets sleeping there. One tip – I would try a leather band next time as the silicone one is awkward to put on with my small wrist.”

Safe and Sound Classic III – Beginner RF Detector

“I have other Safe Living products and bought this one because of its size and convenience. I procrastinated for a while because I have other meters from SLT that I can use instead of this one. This unit is so compact and convenient that I never leave home without it. I can fit it in my shirt pocket, (in the case even), take it out, turn it on, put it in my shopping cart with sound on at the grocery store and it sometimes get some folks attention and some even ask questions that spark-up a good learning conversation for me to share what I know and learn things from them as well, and possibly get some of them thinking different about their surroundings and the world they live in. I’ve been on the EMF journey for many years and have used and bought a lot of equipment in that time, in short, I love this little meter. One more “HUGE PLUS” for me is that it’s made in the US, what a concept, right? Thank you SLT.”
