Maschek ESM-100 Isotropic ELF/VLF Field Strength Meter

The 3D H/E fieldmeter ESM-100 is a patented, unique hand held measuring instrument. It can easily measure electric and magnetic alternating fields simultaneously, independent of their direction, and at one point.

The frequency range of 5 Hz-400kHz covers the main part of the electric and magnetic fields created by power electronics. Very low and very high field intensities as, for example in the operative range, can be measured. Thanks to the possibility of being able to carry out electric field measurements holding the ESM-100 in ones hand, polluted areas can be found very quickly.
