How to Choose an EMF Meter
Not all EMF meters measure the same thing. Here's what to consider before you buy.
RF vs ELF
RF meters detect wireless signals (cell towers, WiFi, 5G). ELF meters detect magnetic and electric fields from power lines and wiring. Combo meters do both.
Frequency Range
Higher GHz range means detecting more modern signals. 5G mid-band operates at 2.5–3.7 GHz, while 5G mmWave can go up to 39 GHz. Most meters cover up to 6–10 GHz.
Ease of Use
Simple dial meters (like the TriField) are great for beginners. Feature-rich meters (like the GQ EMF-390) have a learning curve but offer more data.
Budget
Budget meters ($30–$60) give general readings. Mid-range ($100–$200) are accurate enough for home use. Pro-grade ($250+) add features like frequency counters and data logging.
Check Your City Before You Buy
