Dette er apparatet for de tekniske amatører. Apparaet gir en enkel evaluering av høyfrekvent stråling, og har en audiofunksjon som gjør at man kan høre strålingsmengden. Apparatet gir og en visning av toppverdier i tillegg til gjennomnittsverdier.#
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.
Frequency Range: 800 MHz – 2.5 GHz Measurement Range: Power flux density: 1 – 1999 µW/m2 Accuracy: Basic accuracy including linearity tolerance : +/- 6dB Zero offset and rollover +/- 9 digits Sensor: Logarithmic periodic antenna Audio Analysis: acoustic signal proportional to the field strength with «Geiger-counter-effect» Signal rating: peak value Power supply: 9 Volt alkaline manganese battery (included), average operation time 10 – 12 hours Low-Batt. indication, auto-power-off
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.
Ekte 3D potensialfri måling av elektriske felt. Utvidet frekvensanalyse basert på optimalisert FFT opp til 32 KHz og bredbåndsverdier over 32 KHz. Du kan velge ekte peak målinger i bredbåndsområde. Opsjon: Integrert transientopptaker opp til 1 MHZ med mange timers opptak. Ta en kikk på Gigahertz sine sider for full oversikt! www.nfa-meters.com
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.
3D-LF-Analyser with data logger NFA 1000 for the most in-depth analysis – our masterpiece! Innovative alternative to the ME series based on a superior concept for efficient data acquisition of electric and magnetic fields, extensive long-term recordings of all relevant parameters and facilitated interpretation and documentation of the acquired data. Features: * Real 3D potential-free electric field measurement, patent pending. * 3D measurement of the magnetic field in a truly isotropic point. * Separate recordings of railway and grid frequencies as well as higher harmonics with true RMS valuation (16.6 Hz | 50/60 Hz | 100/120 Hz plus even harmonics | 150/180 Hz plus uneven harmonics | other frequencies < 2 kHz | all > 2kHz) * Measures 110,000 samples per second, the maxima of which are recorded up to 10 times per second on the 4 GB SDHC memory card supplied. Due to the simultaneous and continuous sampling of frequency and axis information you won’t miss even the smallest peaks. * Voice recording of audio notes to facilitate measurement and interpretation of recordings. * Broadband peak measurements (genuine peak of a wave) as a firmware update in preparation. * Optional, in preparation: Wireless data transfer to external display unit /PC. * Supplied with revolutionary PC evaluation software: Super fast real-time presentation, statistic functions (e.g. 95. percentile), analysis tool for Dirty Power. * Li-Ion rechargeable batteries for up to 48 hours of continuous recordings. External power supply possible (power adapter included).

It supports all above mentioned «common advantages». The extra-broad frequency response of the UBB27 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.
