Is Electric Pen reliable when measuring electricity?

The household electric pen is very convenient to use, so it is widely used almost anywhere. the electric pen measures the charge, but can not distinguish between induction and real leakage.  The digital pen has a large deviation from the inductive voltage, so the measured values are not used as a basis for judging specific voltage values. Whether electricity is harmful to living organisms depends largely on the amount of current passing through them. Our actual measurements of induced electricity are well below electrical safety standards
