Advanced Electric Field and Grounding Video

Intermediate Level EMF Meter (5Hz – 100,000 HZ)


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

The ME3840B is designed to meet Building Biology EMF measurement performance requirements  


** Frequency Filter to aid with source identifications

** Extended Frequency Range to 100,000 Hz 


ME3840B EMF Meter Includes:


·         ME3840B EMF Meter

·         Users' Guide

·         2 Year Warranty Certificate

·         Grounding Cable17 foot (5.18 Meters) - for AC electric field measurements

·         9V Alkaline Battery




·       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


Calibration:  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.
