As 5G Free Nelson seeks to purchase an electromagnetic radiation meter for the group, this excellent overview of six popular options by James Chappèll is very valuable.
Gigahertz RF-Analyser HFW35C High Frequency Analyser for Frequencies 2.4 to 6.0 GHz €475.50 plus courier and import duties. Easy to use. Bold easy-read one number read-out. This device will not read anything below 2.4GHz so new ranges of 5G in 700MHz to 900MHz ranges being used for 5G are not recorded. Log-per antenna reads polarity and direction. Easy battery change. Sound output.
Gigahertz HF ANALYSER HF35C range 800MH – 2.7GHz €349.50 Easy to use. Bold easy-read one number read-out. Log-per antenna reads polarity and direction. Easy battery change. Sound output.
Cornet ED88T EMF Meter US$376 + Tri operation mode: RF power mode, LF Gauss mode and LF E-Field mode. RF range: 100MHz to 8GHz (RF meter), (-60dBm to +5dBm),(0.5µw/m2 to 1.8w/m2), 14mv/m to 26.2v/m). Rf (100MHz - 2.7GHz) range. LF1: 50Hz to 10KHz (0.1uT to 60uT)/(1mG to 600mG). LF2: 50Hz to 1KHz (0.01uT to 1uT)/(0.1mG to 10mG). E-field bandwidth of 50Hz-50KHz with sensitivity of 10v/m to 1000v/m. Peak power density measurement 1.5µW/m2 to 0.58W/m2. LCD Backlight: LCD Histogram and bar display. LED scale.
Extech EMF450 Multi-Field EMF Meter Measures Magnetic Field, Electric Field and Radio Frequency Strength US$310.- Pocket size. Trifield measured simultaneously. Triple axis mag fld. Not directional. Easy to read. 3 AA batteries. Sound feature.
Extech 480846: 8GHz RF Electromagnetic Field Strength Meter 10MHz to 8GHz frequency range US$546.95 Triaxial with directional setting. Max & hold. 9 v battery Field strength but no frequency. Rf & e-field. No magnetic. Easy to handle but small text Numbers jump around making direction finding difficult.
Acoustimeter AM-10 RF Meter $170.00 RF and e-field. Simple scales, small text. Read-out shows µW/m2 & V/m. LED scale Sound Very popular.
