The kit containing our three top models, the NFA1000, HFW59D and the HFE59B.

This set consists of our two top models, the NFA1000 and the HFE59B. The quasiisotropic antenna of the HF-device has special advantages for the building biology emission measurements, the identification of so-called hot spots, and additionally extends the analyzed frequency range down to 27 MHz. It therefore also includes the TV- and radio-frequencies, as well as the TETRA standards which are to be introduced all over Europe. The NFA1000 with its 3D sensors for E & M, FFT analysis, and data logger is definitely a convincing instrument.

Due to its extra broad frequency response, this basic device is predestined for an extension with the UBB27 and for detailed, professional analyses. 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 for scientific and industrial purposes - mostly as kit called HF E 59B - especially in the sector of EMVU and product development (precompliance).

Frequency range: A frequency range of down to 27 MHz within the basic device - suitable for the connection of an optionally available antenna (the scope of delivery includes a compensated antenna for 800 MHz up to 2.7 or 3.3 GHz)

Product information "HF-Analyser HF59B"
In addition to the full functionality of the HF58B-r:

A frequency range of down to 27 MHz within the basic device - suitable for the connection of the optionally available antenna UBB27_G3 (the scope of delivery includes a compensated antenna for 800 MHz up to 2.7 or 3.3 GHz).

A calibrated extra AC-measurement output for the demodulated signal, and a scalable DC-output.

HINT: If you only need to measure above 800 MHz the HF58B-r is the cheaper and better solution for you. Only with the antenna UBB27 (included in the kit HFE59B) you can in fact measure frequencies below 800 MHz (e.g. digital TV, TETRA, new GSM Channels in Europe).

Product information "HF-Analyser HFW59D"

HFW59D in its PLUS configuration to supplement the basic building biology equipment for the upper frequency range up to 10 GHz: Especially for the analysis of the two WLAN/WiFi bands, the recently auctioned 5G band and, of course, radar between 8.5 and 9.5 GHz. This device has also been tailored to the building biology needs, and has found rapid worldwide distribution in building biology professional associations since its market launch a few years ago

Also includes modern power adapter radiation
reducible to 400 KHz for TCO measurements.

Exclusive highlights in addition to the 3D magnetic field measurement
THREE-dimensional potential-free measurement of the electric field - without additional "cube" - making the impossible possible thanks to our patents DE102008045360 and DE102007025911.

The potential free measurement of a sleeping area at 9 individual spots is optimally supported by the firmware of the NFA1000 allowing it to be fully completed in less than a minute. With a mouseclick, NFAsoft supplies the frequency and axis specific visualisation of the measurement.
Non-isolated electric field measurement possible with integrated sensor or with the optionally available TCO conform probe TCO3.
An integrated voice recorder facilitates the measurement analysis.

Please have a look at the data sheet (to be found under "available downloads") for detailed descriptions of the broad performance range of this meter, also in comparison to the other NFAs.
Please find the most current version of the firmware under "Downloads" at the top right of the Gigahertz-Solutions site.

Extra components included in the KIT:

Attenuator with DC-Bypass DG20_G10: For the measurement of increased power flux densities (up to a factor of 100).

Ultra broadband antenna for RF-Analysers UBB27_G3: The outstanding parameters with regard to the frequency linearity and the responsitivity render this antenna a very useful equipment for broadband measuring devices for the definition of the total exposure to high frequency radiation.

Frequency range: 27 MHz to beyond 3.3 GHz.

From 27 MHz to beyond 3.3 GHz*: For the measurement of the primary high frequency ranges: CB and amateur radio, directional radio, TV and radio (digital and analogue), TETRA, GSM, radar, DECT, UMTS, WLAN, and more.
"Overall (non-directional) reception": Horizontal isotropic directional pattern - a fundamental feature for long-term measurements.

Compact construction: Identifies so-called "hot spots".
To be attached directly onto the HFE35C or the HF59B.
* Limited in real terms by the frequency response and specifications of the respective HF analyzer.

RF-preamplifier HV10_27G3: Increases the sensitivity of the HF-analyser by a factor of 10 (= 10 dB), that is nominal 0.001 µW/m²*. Adapter plug to be connected to the antenna input socket, remote-fed by the respective basic device. It is especially recommended for the HF59B for measurements in the highly sensitive measuring range of the radar and UMTS mode.

Future-proof: Comprises the full frequency range of the HF59B.
In order to avoid measurement errors due to intermodulations, a high pass filter matching to the antenna (such as the HP800) should be applied when measuring with the log.-per. antenna.
* The actual sensitivity is limited by the device-specific residual noise of the HF-analyser.

High-pass filter HP800_G3: The HP800 increases the measuring accuracy when measuring with the log.-per. antenna in combination with the extremely broad band devices HFE35C and HF59B(Filter included in the scope of supply of the HFE59B). Why? The log.-per. antennas are sensitive also for individual frequencies below the specified frequency range.

These can be successfully suppressed with the filter, which in turn allows a significantly improved analysis of the measurements with a log.-per. antenna, as the measurements are not impaired by unidentified interference signals.

This filter helps suppress the lower frequencies. It reaches an attenuation of more than 50 dB (= factor 100,000) below 600 MHz.
All Gigahertz analysers specified above 800 MHz already come with a similar filter integrated in the basic device. This integration naturally makes no sense for the HFE-types.

Adapter plug to be connected to the antenna input socket.

Plastic Transport Case K2: Universal transport case with shaped foam filler inserts

Dimensions: approx. 33 x 27 x 16 cm.

HFE59B, HFW59D and NFA1000: What distinguishes this combination from all other devices in our range

The HFW59D extends the frequency range to REAL 10 GHz. The preamplifier included in the set reduces the display resolution down to 0.01 µW/m².

Both RF measuring instruments have fully compensated antennas with minimal ripple and a very good compromise between directivity and measuring characteristics. What they both have in common is a maximum VBW of 2 MHz for displaying the shortest radar pulses (< 0.5 µs) with optimized peak hold function (patent no. DE 103 34 886) as well as AC and DC outputs and a battery pack that is clearly superior to the 9 V block.

The HFE59B also includes the 360° Omni antenna UBB27 as a basis for long-term recordings.

The NFA1000 impresses with integrated (!) 3D sensors and recording capability for the magnetic and electric field, an intelligent frequency analysis, especially for "dirty power" and a free signal port for connecting the HFE59B or the HFW59D for recording the HF in parallel to the NF magnetic field.

Particularly important for building biology practice is the principle followed in the NFA 1000 of a display reduced to the essentials during measurement, with parallel recording of a maximum database for later analysis. An audio note recorder links both worlds.

The instruments are supplied in a sturdy plastic case, the moulded foam insert of which protects the instruments perfectly.

It goes without saying that the devices combine all the advantages of our measurement technology, which is summarised here for you once again:

We are especially proud of the fact that all our devices are fully frequency compensated, i.e. all causes of electrosmog pollution are considered exactly according to their actual share in the total pollution. This is the crucial prerequisite for a meaningful measurement, laborious to implement and therefore scarcely encountered in this price class.In addition, our measurement technology always displays the SUM of ALL interfering radio services present at the place of measurement, not just the strongest frequency, as is common in the cheap - allegedly - very broadband detectors that have been launched on the market in recent years. The measured values are displayed reliably and directly in the unit of the building biology precautionary values - without any calculations being necessary. The HF-Analysers are equipped with a fully-fledged LogPer antenna. This clearly sets them apart technologically from compact pocket devices without an external antenna. Their LogPer antennas of the devices allow users to detect and measure even hidden sources of high-frequency electromagnetic radiation (HF). The measurement can take place both indoors and outdoors (protect the meter from moisture!).With the audio analysis, even without electronic expertise, it is possible to distinguish most radiation sources, such as mobile phones, WiFi, DECT, radar, etc., from each other. Simply by listening and comparing with the offered sound examples. The "Geiger counter effect" helps to identify areas of increased LF stress.Detailed measuring instructions with limiting values allow a reliable evaluation of the personal exposure - even without technical expertise.Last but not least: Many patents have been granted to us, the devices have ten thousandfold proven their reliability, and have shown to be leading-edge in their price categories.
