Stay informed about your environment with the Safe and Sound PRO II RF Meter—a professional-grade, easy-to-use broadband RF detector trusted by engineers and health-conscious individuals alike. Designed for both home and field use, this meter helps you accurately assess ambient radio frequency (RF) and microwave radiation from modern wireless devices, including 5G, Wi-Fi, smart meters, cell towers, Bluetooth, and more.

Product Highlights

Wide Detection Range (200 MHz – 8 GHz): Capture signals from most modern RF-emitting devices, including 5G (low & mid bands), Wi-Fi, cellular, smart TVs, Bluetooth, radar, smart appliances, and cordless phones—with true response between 400 MHz and 7.2 GHz (±6 dB accuracy).

Precision & Sensitivity: Measures power densities from as low as 0.005 μW/m² up to 3,180,000 μW/m², providing reliable results for both low-level home detections and intense source measurements. Easy-to-read four-line OLED display gives you peak, max hold, and average readings plus dynamic bar graph for at-a-glance insight.

Distinguish Signal Sources: An integrated audio function lets you “listen” to RF signatures, helping you identify the source of signals—such as distinguishing a Wi-Fi router from a cell tower. Includes speaker with adjustable volume and headphone jack for discreet or public use.

Professional Features, User-Friendly Design: Built-in antenna means no protruding parts; only three controls for setup and operation (power, volume, max reset). Bar graph display and colored LEDs indicate field intensity from “slight” to “extreme” at a glance.

Portable & Durable: Compact (approx. 5.75 x 3.5 x 1 in) and lightweight (about 10 oz), this meter comes with a hard shell carrying case, two AA batteries, and a clear user guide. Battery provides up to 18 hours of use (speaker off), so it’s ready for long surveys.

Continuous Monitoring: Features a USB port so you can power the unit for extended use. Calibration certificate and building biology guidelines are included for professional auditing or health studies.

Typical Uses

- Identify and measure RF exposure from cell towers, routers, Bluetooth speakers, laptops, smart meters, baby monitors, and more.
