  • Tricolour bar and audible alarm warn at 250 V/m, 5 mT or 50 mW/m²
  • One-hand operation uses body grounding for accurate electric-field readings
  • Mute mode and 15-minute auto-off suit quiet or extended use

3-Type EMF Meter with Alarm

The Manw EMF meter measures AC magnetic fields, AC electric fields and microwave radiation in a single handheld unit. A tri-colour bar graph and audible alarm indicate when readings exceed 250 V/m, 5 T or 50 mW thresholds. The backlit LCD remains readable in low light, and the device powers off automatically after 15 minutes unless the auto-off function is disabled.

Homeowners and Field Testers

This meter suits homeowners, families and general users who want a clear indication of everyday electromagnetic exposure from sources such as Wi-Fi, smart meters and household appliances. It is not intended for scientific or industrial testing where calibrated absolute accuracy is required. Buyers needing laboratory-grade precision or data-logging capability should look at specialised instrumentation instead.

Hand-Held Grounding and Power Checks

For accurate electric-field readings the unit must be held in the hand so the body provides a natural ground reference. A standard 9 V battery (not included) powers the device; verify you have a fresh cell before starting a survey. The mute function silences the alarm for quiet environments, and disabling auto-off allows continuous monitoring during longer sessions.
