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.
