Magnii DSP-523 Magnetic Field Meter with "ignores powerlines" setting.

Description

With this meter you can look at just the 50/60 Hz signal, or just the harmonics, or just everything else.
And
you can compare that reading to the overall reading on the same screen at the same time!
Perfect as an all purpose True-RMS 3-Axis meter with high sensitivity. Great for distinguishing a 50 or 60 Hz signal from the higher frequency harmonic signals which often accompany power line magnetic fields.
