The esi 24 emf detector is equipped with internal low-frequency (lf) probes for AC electric field and AC magnetic field, and an internal high-frequency (hf) antenna for accurate RF - microwave measurement.
1) HF microwave and radio wave antenna (blue)
2) three magnetic field coils for 3D Gauss meter function (green)
3) electric field plate for AC electric field assessment (red)
Electromagnetic radiation is also known as radio wave and microwave radiation, high-frequency (HF) radiation, RF (radio frequency), high-frequency electromagnetic fields (HF-EMF). Frequency range of electromagnetic radiation: from about 30 kHz = 30,000 Hertz up to the lower infrared light frequencies, which start from 300 GHz = 300 Gigahertz.
