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).
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.
Product information “TCO konforme Aufstecksonde (NFA) TCO3” For measurements of E-fields in line with the regulations at locations of difficult access, such as bedroom measurements or low-field electrical installation inspections.
