  • Description
The MW 1 makes electro smog caused by pulsed high frequency (mobile phones, cordless DECT, WLAN, WIFI, etc.) audible and thus gives an impression of the exposure in your personal environment.

The volume of the acoustic signal of the MW 1 is proportional to the field strength, and the sound helps differentiate the various sources of radiation. 

  • Perfect for beginners!
  • Straight forward single-knob control.  
  • Dimensions: 147 x 85 x 42 mm 
  • Not suitable for quantitative measurements.
  • Supplied incl. battery and multi-lingual  instruction manual

The HFE35C

It supports all mentioned "common advantages". The extra-broad frequency response of the UBB27 antenna, together with the features and specifications of the HFE35C offer an outstanding overview over the exposure, a determination of suitable remedial actions, as well as a control of their effectiveness.

Set offer including the following components:

  • The instrument itself, based on the HF35C but with an extended frequency range reaching down to 27 MHz.
  • Two antennas: The especially compensated log.-per. antenna for the range above 800 MHz,
  • and the horizontal isotropic ultra broad bandwidth antenna UBB27_G3 from 27 MHz up to far beyond 2.5 GHz (limited by the frequency response of the HFE35C).
  • Small plastic case K5: with convoluted foam filler for a safe transportation of the measuring device and both antennas.

The HFW35C

The "common advantages" are fulfilled by this instrument for the specified frequency range. As simple to operate as the HF35C. Its functions and features are tailored to the needs and practical experiences of the building biology. Due to its comparably low price, it is often also used by computer retailers, authorities and industry for dimensioning of WLAN-networks.

Functionality similar to the HF35C, however:

  • Frequency range from 2.4 to 6 GHz.
  • A special device suitable for the measurement of radiation caused by wireless applications / computer networks, including the new standards (Bluetooth, WLAN, WiFi), also covering the WiMAX-frequencies auctioned off in 2006.
  • It comes with an especially aligned log.-per. antenna with excellent directivity (Patent pending: AZ 10 2006 051 180.8 ).
  • It suppresses frequencies from mobile radios and DECT by means of a steepsided high pass filter integrated into the antenna to avoid falsified measurements of the frequency range from 2.4 to 6 GHz.
  • The instrument is equipped with the switch of the professional line for quantitative differentiation between pulsed and un-pulsed radiation.

Further details upon request.

Regarding the HFEW47C Safelevel scout (under development), the latest news are the following: The production of this device has been delayed (mainly due to the development and production phase of the NFA series). This delay has given us opportunity to find out that in fact a set consisting of the two devices HFE35C and HFW35C makes much more sense than producing this new device, as this combination is much more effective. Let me try and explain the advantages: Both devices which form part of this set have a log-per antenna allowing a localisation of the source of radiation (the HFEW47C does not have a log-per antenna). The isotropic antenna of the HFE35C only covers about 3 GHz, which means that the higher levels can only be evaluated with the log-per antenna. This can be considered a slight disadvantage, but is equated by the fact that not so many frequencies are to be found in this range. A further advantage of the set is that with the help of the steep slope filter in the HFW35C WLAN and other higher frequencies can be clearly separated from the dominating frequencies of the HFE35C. Furthermore, the HFW35C has an extra switch allowing to see the pulsed signals only, resulting in a clearly increased resolution. This, in turn, is very useful with regard to the often low field strengths in this range (which can be considered important as they are pulsed with approx. 10 Hz, a frequency considered especially relevant by building biologists).

The HFEW47C was meant to start measuring at 3 MHz. The purpose was to cover the DLAN in households (data communication via the networks at 3-5 MHz). With the current field measuring devices this is technically impossible, yet devices with specifications as of 1 MHz are offered on the market at low price, and when specifying the measuring ranges of the HFEW47C we caught this "virus". Yet, after having taken into consideration all details, we have decided to stick to a measuring technology which is able to offer realistic and practical results for the user, which is why we have decided to go for the above mentioned set solution.
