In order to achieve the end goal of "healthier sleep", various changes in the bedroom are usually necessary.
The question is which changed. This is why we offer the service of a geobiological assessment.
This enables a targeted mitigation and avoids unnecessary costs. After this assessment
you receive the status ‘patient’ in our system, which gives you a significant price advantage

HF digitmeter specially developed for geo- and building-biological analyses

The HF-Digitmeter has been specially developed for geo- and building-biological analyses and is intended to explain in a self-explanatory way from which analysis values a load is present.
Medical and environmental medical experience of the last 30 years have been used for this purpose.

  • Large digital display instrument with acoustic output
  • Easy handling
  • Measuring range up to 8 GHz
  • Detection of electrical radio frequency fields and transmitters, e.g. in residential and sleeping areas
  • Recording of stress values by body coupling (for professional geobiological analysis)
  • Fast location of Wi-Fi and DECT
  • Loudspeaker stouming frequencies also in tone form.
  • Reliable tool for the professional, fast instruction of laymen, e.g. patients, possible


Electric field

By means of the plugged-in measuring antenna, high-frequency fields can be measured in a microvolt.
A major advantage is that not only air can be measured, but also body couplings of persons are possible.
Especially in the case of geobiological measurements, the exposure of persons is of important importance here.

The body acts as an antenna in this procedure and collects all frequencies that affect it.
The RF digitmeter represents the collected frequency spectrum of 10 MHz – 8 GHz in microvolts.

The field strength (HF) increases or decreases due to:

• Distance to the EMF polluter
• Performance of the polluter
• Type, structure and orientation of the polluter
• Influence of transmitters in the vicinity

The tone frequency and key change with increasing EMF intensities and type of transmitter.

Difference In building biological measurement vs. geobiological measurement

In the case of the building biological measurement (W/m2), the (outgoing) performance of the polluter/transmitter and thus the air measured. A body coupling is not provided / possible here.
In the case of geobiological /medical measurement (µV) the (incoming) electrical voltage.
This is particularly interesting, since by attacking the antenna (enlargement of the antenna by the corresponding person = body coupling), can now be estimated, with what intensity the body and the nervous system. This type of measurement has been referred to as “medical measurement” since the 1990s. In this measurement, the body-compatible values should, if possible, be below 30 µV (target) are.
If this is not possible and the displayed values are too high, an RF shielding according to Faraday is highly recommended! More information on www.geovital.com
After successful shielding, the values should go down significantly and at best settle in the body-compatible range of less than 30 microns. Once this is achieved, the figure in the display will show you OK.


The HF digitmeter has a LiPo battery. The battery status is indicated by a battery icon.

2,5 GHz Pass filter – For the reproduction of measured values according to the old measuring method of the Hengstenberg Digimeter

At the end of the 1990s, Hengstenberg’s device had established itself as a standard for the measurement in microvolts. Mainly physicians and environmental physicians used this measuring device to obtain an assessment of the body load of patients. The Hengstenberg HF-Digitmeter became the standard measuring device for geobiologists. All umbrella standards known to geobiology have been developed with this device over the last 20 years.
In 2012 the production of the old Hengstenberg HF-Digitmeter was discontinued.
Since there was no successor device and no other manufacturer could be found who wanted to develop a successor device, GEOVITAL jumped into the breach and started a 250,000,- Euro program to develop an RF device that works according to the old Hengstenberg measuring method. After 4 years of development, this has been ready and in use since 2016.
On the old HF digitmeter of Hengstenberg it is indicated that a measuring range of 4 GHz is possible, but physically the measuring range is limited by the building materials used. Since stainless steel was used as measuring components and antennas, the usable measuring range is only 2.65 GHz. Stainless steel cannot detect higher frequency ranges. Laboratory measurements have a realistic maximum range of 2.4 – 2.5 GHz.
The new GEOVITAL RF digitmeter is designed for frequency ranges up to 8 GHz. The reason why no higher design was chosen is solely due to the affordability of the components and measuring electronics, which would otherwise have become excessively expensive, since these would be high-priced individual productions.
In order to build on the old experience values of the last 20 years and to represent a comparability of the old and the new RF digitmeter, the new RF digitmeter can be reduced to this frequency range by means of the 2.5 GHz pass filter. This is interesting in that environmental physicians have agreed on maximum parameters used in the control of shielding materials during this period.
In order to be able to continue to control this, the possibility of the old Hengstenberg measuring method must also be possible with the new HF digitmeter.
