Equipment

ELF fields
Narda EHP-50F E&H field analyser
  • Electric and magnetic field measurements in the frequency range 1 Hz to 400 kHz (including 50 Hz mains).
  • Isotropic (3-axis) or single axis measurements.
  • Spectrum analysis of harmonics.
  • Complex waveforms evaluated using the "weighted peak" method if required
  • Data logging
See examples of this meter used to measure fields from transmission lines and induction cooktops.

RF fields
Narda SRM-3006 with triaxial E-field probe
  • Narrowband electric field measurements at frequencies from 30 MHz to 3 GHz (covers all FM radio, TV, cellular transmitters).
  • Contributions from individual transmitters to total exposure can be evaluated.
  • Exposures from cellsites can be accurately extrapolated to determine maximum exposures.
  • Data logging
See examples of this meter used to measure environmental RF fields, WiFi and a cordless phone base station.

Narda EHP-200A E&H field analyser 
  • Narrowband electric and magnetic field measurements at frequencies from 9 kHz to 30 MHz (covers industrial heating and welding equipment, AM and short wave radio transmitters etc).
  • Contributions from individual transmitters to total exposure can be evaluated.
Narda NBM-550 broadband meter with EF 0691 and HF 3061 probes
  • Broadband electric field measurements at frequencies from 100 kHz to 6 GHz.
  • Broadband magnetic field measurements from 300 kHz to 30 MHz.
  • Isotropic or single axis measurements.
  • Data logging.
ETS-Lindgren HI-3702 induced current meter
  • Measures limb currents at frequencies from 9 kHz to 70 MHz.
  • Maximum hold capability to check contact currents.
