An innovative step forward in the scope of LF analysis: The NFA 1000 is both, a precise 3D magnetic field logger as well as a high-resolution potential-free E-field cube, all in one meter among the professional devices (patented technology) supported by the comforting certainty of having the complete technical expertise of Gigahertz Solutions behind it.
The essence of all devices is a high-capacity processor able to analyze the field situation with an axe-specific FFT and a sampling rate of 110,000 data records per second, and to record all data on a standard SD-card. It is furthermore possible to connect external probes, and to simultaneously record the corresponding measurement values (available for high frequency and for static fields).
The easy to operate PC program NFAsoft with its revolutionary statistical functions as well as evaluation functions provides a quick overview and if necessary an analysis down to the last detail.

Skittenstrømfilterene demper støy fre det elektriske anlegget ved at den fjerner uheldige frekvenser som rir på de rene sinusfrekvensene i strømnettet. Det er særlig sparepærer, lysstoffrør og alt av elektronisk utstyr som lager disse frekvensene. Skittenstrømen måles med en skittenstrømmonitor som puttes i vegguttaket. Man legger til filtere i den sammme kretsen til den ønskede effekten er oppnådd.
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. antennae 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. – Adaptor plug to be connected to the antenna input socket.
Technical data: – Accuracy: Attenuation: 10 MHz – 600 MHz < – 50 dB – Pass band: 0 Hz, 800 MHz – 3000 MHz = -1 dB +/- 0.5 dB – Return loss: > 12 dB – Further Questions: Two years warranty – Weight: 0,03 kg
Scope of delivery: – High-pass filter – tightening aid – manual

This is THE device for technical amateurs – especially easy to operate. It allows a straight forward assessment of the exposure, a determination of suitable remedial actions, as well as a control of their effectiveness. Even this starter device already combines all common advantages. The reading shows the total pollution without any calculation required. The measured values are reliably displayed directly in the entity corresponding to the building biology standard values. An acoustic signal proportional to the field strength with “Geiger-counter-effect” helps identifying regions with increased exposure. Digital display of 1 µW/m2 up to 1999 µW/m2.

Low frequency analyser ME3830B– for an easy evaluation of LF-exposure
This is THE device for technical amateurs – especially easy to operate. It supports all above mentioned “common advantages” and it allows a straight forward assessment of the exposure, a determination of suitable remedial actions, as well as a control of their effectiveness.
Comprises all features of the ME3030B, and additionally offers:
A clearly extended frequency range: from 16 Hertz to 100 Kilohertz. This frequency range (in accordance with SBM) also includes the higher frequencies caused by, for instance, energy saving lamps, switching-mode power supplies, electronic dimmers, or monitors, which are considered especially critical.
Dette er linken mellom amatør og profesjonelle måleapparater. Dette er apparatet for leger og alternative praktikere.Den har alle de samme funksjonene som 35C men en høyere respons og sensibilitet. # 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.
