The Safe and Sound Pro II RF Meter is widely considered the best consumer-to-professional grade radio frequency (RF) meter because it covers a broad frequency range (200 MHz to 8 GHz) and was independently tested and certified by the CIARS Lab at the University of Waterloo.

How Do You Know It Is the Best?

• Independent Laboratory Testing: Certification from an accredited university antenna lab ensures its stated sensitivity and frequency responses are accurate rather than marketing claims.
• High Sensitivity: It detects very low-level signals down to 0.3 µW/m², making it effective for measuring distant cell towers or intermittent smart meter pulses.
• Audio Signature Analysis: It includes a headphone jack and speaker with distinct sound signatures that allow you to audibly identify the specific source of radiation (such as Wi-Fi versus cell towers).
• Multiple Measurement Modes: It displays peak, maximum hold, and average readings in µW/m², satisfying both human-exposure sensitivity checks and compliance standards.
