these tests apply one clean signal of a single frequency at at time.
under real world circumstances the performance is quite another story.
from a distance this "safe and sound" meter looks like expensive garbage to me.
most rf-meters are far from accurate below 700 MHz, whatever may be claimed.
above 3 GHz it is usually not much better.
the rf-explorer gives some value for money including reasonable spectrum analysis.
the sound of the esmog spion helps finding many sources of emfs.
e.g. a central heating boiler may produce a strange peep on the esmog spion.
no other meter that i know off will detect this LF field.
it is an amazing instrument but a bit fragile built.
a new model will be launched in august (!).

pretty exciting after decennia of beating other new meters with its old model.
