Gigahertz Solutions ME3830B

Frequency coverage by mode

One band per measuring mode, as the manufacturer states it.

magnetic flux density

16 Hz – 100 kHz, switchable 16 Hz – 2 kHz band

electric field strength

16 Hz – 100 kHz, switchable 16 Hz – 2 kHz band

Display range by mode

AC magnetic flux density

displayed in nT, with the building-biology target under 200 nT and preferably under 20 nT

AC electric field strength

displayed in V/m, potential-referenced or potential-free

Calibration

Manufacturer factory calibration; recalibration is offered by Gigahertz Solutions. No accredited certificate is supplied with the meter.

Suited to

• Bedroom and workplace surveys of wiring, transformer and appliance fields, including the potential-free electric-field method building-biology protocols ask for
• Splitting a reading between the mains band and the harmonic/VLF band with the 2 kHz filter, which is how a dirty-electricity contribution shows up
• Tracing a field back to a circuit by ear while a second person switches breakers

What it cannot do

• Not an RF meter: nothing about Wi-Fi, cellular, smart meters or cordless phones can be measured with it
• A single-axis sensor, so a true magnitude needs the instrument rotated through all three room axes and cannot be read in one shot
• No logging, so an overnight or 24-hour record needs the maker's NFA series or an external recorder
• Electric-field readings depend on the measurement method and on where the operator stands; the potential-referenced and potential-free figures are not interchangeable

What these figures are

Every number on this page is the manufacturer's own declared specification, reproduced so that models can be compared field by field. Nothing here is an independent test of the instrument, a calibration certificate, or a statement that a reading taken with it can be compared with a regulatory limit — that depends on the detector, the averaging and, where it matters legally, an accredited calibration.

• ELF gaussmeter (power-frequency magnetic field)

  Measures 50/60 Hz magnetic flux density in milligauss or microtesla — the instrument for wiring faults, service panels, transformers and power lines.

  Instruments

• AC electric field meter

  Reads power-frequency electric field strength in V/m, the quantity that reveals energised wiring behind a bed head even when no current is flowing.

  Instruments

• Intermediate-frequency magnetic field meter

  Covers the kilohertz gap between an ELF gaussmeter and an RF meter — the band occupied by induction hobs, EV inverters, solar optimisers and switch-mode supplies.

  Instruments

• ELF magnetic field survey

  A source-finding walkthrough plus a 24-hour log, because power-frequency magnetic fields track electrical load and a spot reading answers almost nothing.

• Sleeping-area assessment (full four-quantity survey)

  The combined survey building-biology practice applies to a bedroom: RF power density, AC magnetic field, AC electric field and body voltage, each graded against its own band.
