BenchPicked data
EMF meter field-coverage matrix
Published field modes, frequency ranges, axis context, accuracy statements, and measurement boundaries for consumer screening meters.
What the data represents
The matrix separates field mode, frequency range, axis context, published accuracy, and consumer-screening use so a broad label such as EMF meter is not treated as proof of equivalent coverage.
Published specifications describe instrument scope. They do not establish BenchPicked-measured accuracy, medical risk, shielding efficacy, or professional compliance suitability.
