The ME3840B, the digital ELF-VLF Meter for Electric & Magnetic Fields 5Hz-100,000Hz (100kHz), with special filters/frequency bands
The ME3840B is the link between non-professional and professional equipment. It is especially popular among medics and other professionals as it is easy to use, while providing professional measurement.
What's special about the ME 3840B is its additional Frequency Analysis. AC fields are not only defined by their field strength, but also by the frequency with which the polarity of the field changes. The ME3840B can separate the following common frequencies and frequency bands:
1) 5 Hz to 100 kHz - Good for overall survey purposes
2) 16.7 Hz - for overhead railway wires in Germany, France, Norway, Austria, Sweden and Switzerland.
3) 50 Hz to 100 kHz - Electric the general power grid and its harmonics.
4) 2 kHz to 100 kHz - “Artificial harmonics” above 2 kHz (e.g. from many AC-adaptors, energy-saving bulbs, TV-sets). This corresponds to band 2 of the Swedish TCO guideline. A factor 10 lower safe limits are recommended for this range.
