HF35C

This device allows a straight forward assessment of the exposure, a determination of suitable remedial actions, as well as a control of their effectiveness.  Easy to operate, the favourite of lay-persons.

Proven ten thousandfold worldwide: Even this most economical device meets the high quality standards of the entire series

• The measured values in the relevant frequency range are displayed reliably and accurately in the unit of the building biology standard - without any calculations being necessary.

• The "Geiger counter effect" and the directional antenna to locate areas with an increased exposure.

• Only with the audio analysis (HF35Cand higher) is it possible to apply specific correction factors for signals with a high crest factor.

• Detailed measuring instructions with limiting values allow a reliable evaluation of the personal exposure - even without technical expertise.

• Many patents have been granted to us, the devices have tenthousandfold proven their reliability, and have shown to be leading-edge in their price categories.

• Digital display from 1 µW/m² to 1999 µW/m².

This is why the HF35C stands out positively from competing products in this price range:

• It is fully frequency compensated, i.e. no frequency range is overrated, underrated or even ignored.

• In addition, our measurement technology always shows the SUM of ALL existing radiation at the place of measurement, not only the strongest signal, as is the case with the cheap - allegedly - very broadband detectors that have been launched on the market in recent years.

• The two features mentioned above are extremely important for a meaningful measurement and technically very difficult to implement. This is also the reason for the unique position of our instruments in their respective price class.

• With the audio analysis of the HF35C, even technical laypersons without electronic expertise can distinguish between most radiation sources such as mobiles, WiFi, smart meters, radar, etc. Simply by listening and comparing with sound examples provided on our website.

• Factor 10 more sensitive than the HF32D (display resolution: 0.1 µW/m², (maximum 1999 µW/m²). The high-resolution is for electrosensitive persons (EHS).

• Measures peak and average values (switchable).
