Magnetic field emission detector
Web8 apr. 2024 · 3. ERICKHILL EMF Meter. If you’re specifically looking to detect lower-level signals, then this EMF meter from Erickhill is an affordable option worth considering. Unlike the GQ and Trifield options, this detector does not scan for radio frequencies, but it does scan for electric and magnetic fields. WebWe measure bio-magnetic field strength in 37 subjects with this detection system. The only 3 subjects of them exhibited strong bio-magnetic field of 2 to 4 mGauss in frequency range of 4 to 10 Hz. This magnetic field strength was greater than that of normal human bio-magnetism by 1,000 times at least.
