Gigahertz Solutions EMF Meter 800 MHz - 2.5 GHz (3.3 GHz with increased tolerance)

The link between amateur and professional instruments.

This device supports all above mentioned "common advantages". It is especially popular among medics and alternative practitioners, as it offers a perfect combination of easy handling and professional measurement possibilities.

It allows an easy allocation of the electrosmog frequencies to the traction power or the mains power as well as to the artificial harmonics, thus facilitating an especially precise consultation of remedial actions and an easy control of their effectiveness.


Has the same features and configuration as the HF35C, however additionally offers some important professional features:

  • The log.-per. antenna with further improved frequency response.
  • A 10 times higher sensitivity: Minimum display resolution 0.01 µW/m² .
  • A measuring range extended upwards by a factor of 10: max. 19.99 mW/m² .
  • Clearly simplified measurements with the help of the "peak-hold"- function.


Technical data:
