The Kaltman Creation's NF5020 measurement of electric and magnetic fields in
this price range has never been this professional. Find radiation sources in
your surroundings. Find their respective frequencies and signal strengths,
including direct display of exposure limits. This used to be impossible in this
price category, professional units often costing several thousand of dollars and
being excessively complicated in handling. The highly complex calculations in spectrum analysis includes exposure limit calculation, which is being performed, unnoticed in the background, by a high-performance DSP (digital signal processor). Professional EMF measurement devices use a frequency dependant measurement approach, the so-called spectrum analysis. In a certain frequency range, the individuals signals and their respective strengths are being broken down, for example into a "bargraph" display. The height of the individual bars represents the corresponding signal strength. For the 3 strongest signal sources, the NF5020 can automatically displays the frequency and signal level, thanks to its "Auto Marker" feature. Of course, you can also setup the filter width and the frequency range to be analyzed as you like. In the EMF (LF) spectrum, a frequency range of approx. 20Hz to 60Hz from left to right is being analyzed. During analysis, the Auto Marker feature has determined - fully automatic - two main signal sources: Signal#1=30Hz at 45µT Signal#2=50 (mains power) at 75µT |

For serious measurements, the NF-5020 measurement devices, with
datalogger, allow long-term recordings of measurement results over a
freely adjustable period of time. This is particularly indispensable for
serious evaluation of exposure by appliances and machinery which have a
changing power consumption or radiation strength over time. Examples for
these include railroads, power lines and plants, but also home
appliances and their respective power cables, and various high-frequency
transmission facilities like mobile phone transmission towers, mobile
phones, radar etc. Depending on the time of day, considerable variation
of exposure can occur (see attached graphics). Without long-term
recordings, massive misinterpretation of total exposure can occur. With
long-term data logging using NF5020, the daily variation of exposure can
be recorded and analyzed. Thus, the ACTUAL total exposure can be
evaluated precisely. With this functionality, you can even discover
sporadic EMC problems which would otherwise be very hard to detect. Even though NF5020 power units "only" last 4 or 7 (depending on model) hours with one battery charge, the intelligent "Power down mode" enables much longer data logging and measurement time spans. Finally, if this is not enough, the external power supply can be used to extend the recording time span infinitely. The exposure limit calculation used to be a complex and awkward procedure even for the professional, as most of the time, a chaotic mixture of an abundance of different frequencies, modulations and signal strengths is present. The indispensible, highly complex calculation of frequency-dependant exposure limits can ONLY be performed conforming to standards by a spectrum analyzer with high-performance software. Not a problem for the NF5020, as it can calculate even several authoritative exposure limits, precautionary limits and recommendations (simply selectable via a button) and display these as a practical bargraph display (including convergence display in percent), while the measurement is running. The attached NF5020 screenshot demonstrates how it works: At the push of a button, the ICNIRP exposure limit has been chosen among the various available exposure limits. NF5020 now automatically calculates convergence or excess of this limit. For achieving this, often thousands of complex calculations have to be performed per second, and a steady scan of the entire frequency range needs to be performed. A true nightmare for every processor. |

Mismeasurement caused by wrongly adjusting the measurement device in space
or troublesome and complex 3D calculations with a calculator are a
problem of the past from now on, thanks to NF5020 EMF (LF) measurement
devices. All NF5020 EMF measurement devices can measure magnetic fields
directly in 3D. The field strengths of the individual X, Y and Z axes
can even be shown separately. The high-tech REAL 3D miniature sensor
coil. Consisting of a specially crafted nylon base with 3 independent
windings made of ultra-thin, 0,05 mm wire, it impresses with its
extremely high sensitivity. It allows measurement of magnetic fields in
all 3 spacial dimensions. The signal processor (DSP) of the NF5020
performs the resulting highly complex calculations. You receive 3D
measurement results which can otherwise only be achieved by using highly
professional equipment. |
