Meters
Compact, Handheld Solution for AC Magnetic Field Measurement


The EF-401 is a cost-effective, handheld AC magnetic field meter designed for quick assessments of electromagnetic radiation from common sources like power lines, wiring systems, motors, and electronic devices.

The EF-401 Magnetic Field Meter delivers simple, accurate, and fast readings of AC magnetic fields across a single axis. Ideal for electrical professionals, safety inspectors, and maintenance personnel, this tool helps you pinpoint and evaluate electromagnetic field (EMF) radiation in residential, commercial, and industrial environments. No external probe required – simply hold or place the device in the field area to measure.
