EMF Electromagnetic Radiation Meters
The term EMF (ElectroMagnetic Fields) covers all fields emitted by sources carrying current or radio waves. They are generally divided into:
- ELF Electric Field: Low-frequency electric fields (50/60 Hz) from sockets and cables
- ELF Magnetic Field: Low-frequency magnetic fields from current, transformers, household appliances
- DC Magnetic Field: Static magnetic fields from permanent magnets or DC current
- RF Radiation: High-frequency radiation from Wi-Fi, mobile phones, antennas
- Electrostatic Field: Static electric charges (ESD) in electronic environments
Which instrument measures what?
| Need | Recommended type |
|---|---|
| Home check (Wi-Fi, sockets, refrigerators) | Tri-mode or ELF+RF Meter |
| Measurement near power lines or PPC substations | ELF Magnetic Meter |
| Radiation check from wireless devices | RF Radiation Meter |
| Measurement of static magnets / DC | DC Magnetic Meter |
| Check of electrostatic charges (ESD) | Electrostatic Meter |
Common for the filters:
- Field Type: What it measures (Electric, Magnetic, RF, Static, etc.)
- Frequency: ELF, DC, RF, or Broadband
- Application: Where you will use it (home, factory, laboratory)
- Features: Device features (3-axis, external sensor, logging)
- Measurement Units: Which units it displays on the screen
