3D-Magnetic field analyser with data logger NFA 30M

for a most in-depth analysis



Allows long-term measurements as required in the standard values for bedrooms (SBM). It is based on a superior concept for efficient data acquisition of magnetic fields, extensive long-term recordings of all relevant parameters and an easier interpretation and documentation of the acquired data. The photo shows the optically identical NFA 1000, as a photo of this device is not yet available.



Features:

3D measurement in a truly isotropic point.

Separate recording of railway and grid frequency 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 > 2 kHz).

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.

Input jack to record an external HF-Analyser.

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 recording. External power supply possible (power adaptor included).
