Gigahertz Solutions ME3840B

Are you ready for a meter with more complex EMF detection capabilities without giving up the ‘easy use’ and ‘best accuracy’

  • The ME3840B offers all the features of the previous models plus a frequency filter to aid with source identification
  • Captures low frequency sources down to 5 Hz
  • 98% accuracy in a frequency range of 5 Hertz to 100 000 Hertz translates into source identification confidence – best frequency detection in its price range
  • Capture all low frequency polluters, sources such as all standard household appliances, electrical wiring and wiring errors, power lines and transformers
  • Identifies higher frequency sources such as all energy efficient appliances, fluorescent and compact fluorescent lighting, dimmer switches and computer monitors
  • Evaluates electrical aberrations such as dirty electricity and power line transients
  • All Gigahertz Solutions EMF Meters are backed by a 2 year manufacturer’s warranty
  • Frequency Filter to aid with source identifications
  • Extended Frequency Range to 100,000 Hz


  • Frequency Filter: built in, F1B2H31 frequency filter: four filter settings that provides manual frequency analysis:
    • 5 Hz to 100 KHz – Complete frequency range of meter – Best suited for tripod measurements
    • 16.7 Hz – Electric Railway (Europe Only)
    • 50 Hz to 100 KHz – Typical measurement setting – Captures low and high frequency emissions
    • 2 KHz to 100 KHz – High Frequency Transients and “Dirty Electricity”
  • 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
  • Power Supply: 9 Volt alkaline battery included
  • Battery Low Indicator: meter will auto-power off 3 minutes following battery low signal display
  • Operating Time: alkaline disposable provides 24 – 36 hrs of continuous EMF testing
  • AC Electric Field: Value displayed in Volts per meter
  • AC Magnetic Fields: Value displayed in nT. Note: 100 nT = 1 mG (conversion table on back of unit for convenience)
  • Single Axis Measurement: Beneficial for source detection


  • Gigahertz Solutions ME3840B EMF Meter
  • Users’ Guide
  • 2 Year Warranty Certificate
  • Grounding Cable – 17 foot (5.18 Meters) – for AC electric field measurements
  • 9V Alkaline Battery

Optional Carrying Case:

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


During the manufacturing process strict calibration procedures are followed using only high end, calibrated measurement instruments. This guarantees that every ME3840B meter made by Gigahertz has been individually calibrated to a traceable standard.
