Gigahertz Solutions ME3951A

Electronic innovations as well as manufacturing trends towards energy efficiency and high performance have created unprecedented assessment challenges for EMF technicians. The extended frequency capability of the Gigahertz Solutions ME3951A Meter provides a measurement solution for the increasingly high frequency ranges produced by new technologies.

  • 5 Hz to 400 KHz, a frequency range unmatched by any other meter in its price range
  • Single axis measurement combined with easy peak value readings puts detection control in the hands of the technician by facilitating source direction identification
  • F1B2H31 built in frequency filter provides three filter settings that manually isolates frequency clutter which allows for source identification accuracy
  • AC/DC outputs provide hook up to specialized equipment for functions such as data logging, full audio assessments and full spectrum analysis
  • A manufacturer's calibration certificate and a self test mode translate into reliable measurement and verifiable accuracy
  • Includes a NiMH rechargeable battery and charging unit
  • Precise potential free (without a ground) measurement option
  • Plastic Carrying case included
  • All Gigahertz Solutions EMF Meters are backed by a 2 year manufacturer's warranty


  • Auto Power Off: saves on battery use – will auto-power off after 40 min of continuous EMF testing
  • Audible Tone: audio assessment - audio signal proportional to field strength – (Geiger Counter Effect)
  • LCD Display: easy to read 3.5 digit display
  • Frequency Filter: built in, F1B2H31 frequency filter: four filter settings that provides manual frequency analysis:
    • 5 Hz to 400 KHz – Complete frequency range of meter – Best suited for tripod measurements
    • 16.7 Hz – Electric Railway (Europe Only)
    • 50 Hz to 400 KHz – Typical measurement setting – Captures low and high frequency emissions
    • 2 KHz to 400 KHz – High Frequency Transients and ``Dirty Electricity``
  • AC/DC Outputs: facilitates equipment interfacing: oscilloscopes / spectrum analyzers/full audio assessment / data logging (0.5 mV DC per digit)
  • Power Supply: rechargeable battery (NIMH supplied) – compatible with 9 Volt alkaline battery
  • Battery Recharging Unit: 12 VDC battery charger supplied
  • Battery Low Indicator: meter will auto-power off 3 minutes following battery low signal display
  • Operating Time: NIMH provides 6 to 8 hours continuous use. Alkaline disposable provides up to 24 hrs continuous EMF testing
  • Self Test Mode: a ‘test for zero’ setting - verifies measurement accuracy and meter calibration (please refer to product manual for a more detailed explanation)
  • Carrying Case: sturdy plastic storage/carrying case included
  • AC Electric Field: Value displayed in Volts per meter
  • AC Magnetic Fields: Value displayed in nanoTesla ``nT``. Note: 100 nT = 1 mG
  • Single Axis Measurement: Beneficial for source detection


  • Plastic Carrying Case – K5 (33 x 27 x 8 cm) (13 x 10.6 x 3.2 inches)
  • ME3951A EMF Meter
  • Users' Guide
  • 2 Year Warranty Certificate
  • Grounding Cable – 17 foot (5.18 meters) - for AC electric field measurements
  • Grounding Clip – For direct connection to water pipe
  • 120 VAC Battery Charger (220 VAC charger available on request)
  • 9 V Rechargeable Battery with charger/power supply

Optional Carrying Case:

  • Interior Dimensions: L=18cm x W=8cm x H=3cm
  • Exterior Dimensions: L=20cmx W=10cm x H=4cm

Calibration Certificate:

During the manufacturing process, strict calibration procedures are followed using only high end, calibrated measurement instruments. This guarantees that every ME 3951 meter made by Gigahertz has been individually calibrated to a traceable standard. An Official factory calibration certification and data is available upon request for a fee of $ 211.00 CAD. This would be considered a custom order and an additional 2-3 weeks is required for this process.
