Safe and Sound Pro II RF-EMR Meter is a good choice for measuring Wi-Fi, 3G, 4G and 5G frequencies (from 600 MHz to 10,000 MHz) that S4WT recommends is the following:

“Use only the peak and max (maximum of peak values detected since the meter was turned on, sometimes referred to as “peak hold“) values when considering the biological effects of pulsed, data-modulated, Radio-frequency Electromagnetic Microwave Radiation (RF-EMR). The average reading is provided as a reference to [FCC and wireless] industry standards that consider only average power levels and their thermal and heating effects on tissue.”
