Here are some instruments that I've found:
*
AlphaLab Trifield 100XE meter: measures all three types of electromagnetic field: AC magnetic field, AC electric field, and radio (including microwaves). The magnetic and electric detectors are 3-axis
*
TES 593 meter: to measure electrosmog 10Mhz - 8GHz. Sensor type is electric field, isotropic, 3-dimensional.
*
magnetic sciences MC162: 2 kHz to 1 MHz AC magnetic field sensor, with BNC connector.
*
magnetic sciences 6GHz EMI probes: wideband single-axis probes allow low-cost measurement of magnetic and electric field strength, locating sources of electromagnetic interference (EMI) and radio frequency interference (RFI), microwave emissions, electromagnetic compatibility and EMC / EMI / RFI testing, and troubleshooting RF circuits.
*
AlphaLab UHS2: AC magnetic field meter, 13 Hz to 75 kHz, true 3-axis magnitude.
*
Gigahertz Solutions RF-ANALYSER KIT HFE35C: EMF meter 27 MHz - above 2.7 GHz.
*
EMFields AM-10 acoustimeter: microwave detector ranging 200 MHz - 8GHz. Has visual scales, LCD screen and speaker.
*
KEYSIGHT FIELDFOX and HSA: handheld spectrum analyzers, ranging from 5kHz to 50 GHz.
*
EMDEX Lite Magnetic Field Meter: Versatile Personal Magnetic Field Measurement System. 0.1 - 700 mG(0.01 to 70 ?T). 40 - 1,000 Hz. True RMS.
