User-Friendly VLF ELF EMF Meter with Professional-Grade Capabilities

The ME3840B is a cutting-edge EMF meter specifically engineered for comprehensive measurement of EMF/LF electrosmog caused by various sources, such as household and building power supplies, high-voltage power lines, electric rail systems, and more. This versatile device functions as a low-frequency EMF meter, ELF reader, and ELF meter, offering ease of use without compromising professional-grade measurement accuracy. The ME3840B is highly regarded by medical professionals and industry experts alike.

Precision Frequency Analysis EMF Meter for Reliable Dirty Electricity Detection

The standout feature of the ME3840B is its integrated Frequency Analysis capability. AC fields are characterised not only by the strength of the field but also by the frequency of polarity changes. The ME3840B expertly differentiates between the following commonly encountered frequencies and frequency bands:

  • 5 Hz to 100 kHz: Ideal for general surveying purposes
  • 16.7 Hz: Specific to overhead railway wires in Germany, France, Norway, Austria, Sweden, and Switzerland
  • 50 Hz to 100 kHz: Addresses the general power grid and associated harmonics
  • 2 kHz to 100 kHz: Targets "artificial harmonics" above 2 kHz, commonly found in AC adapters, energy-saving bulbs, and TV sets, following the Swedish TCO guideline's Band 2. A factor of 10 lower safe limits are recommended for this range.

Advanced Features for Precise EMF Measurements and Dirty Electricity Detection

In addition to the capabilities of the ME3830B, the ME3840B is equipped with a switchable internal filter module similar to those found in professional-grade devices. This feature enables users to numerically differentiate between various EMF pollution sources, such as Dirty Power, mains supply, and traction power. The ME3840B is essential for adhering to the stringent Building Biology recommendations, particularly for the frequency range from 2 kHz and above, also known as "Dirty Power."

State-of-the-Art Functions for Superior EMF Protection

The ME3840B measures magnetic and electric fields using scientifically validated methodologies, delivering exceptional sensitivity (display resolution: 1 nT or 1 V/m). The "Geiger counter effect" aids in pinpointing areas with elevated LF stress. Comprehensive measurement instructions are included, empowering users to conduct accurate EMF measurements without requiring prior technical expertise. This device detects concealed sources of LF pollution. Its accompanying manual offers recommendations for limiting values per the standard of building biology SBM, allowing users to assess their personal EMF exposure levels accurately. Gigahertz Solution devices have been granted numerous patents, have demonstrated their reliability in thousands of applications, and consistently outperformed competitors in their price range.

    The meters supplied by Anti-Radiation are manufacturer calibrated and are suitable for general use. Customers who wish to use our meters for certain types of formal testing, for example occupational EMF assessment to meet the needs of the UK HSE or EU EMF Directives, will most likely need to arrange for certification of individual units at an approved calibration facility. This type of certification is a common requirement  for many types of test equipment, not just EMF meters.

    • This meter is for Power Frequency (ELF) EMFs - please see my other items for RF meters suitable for measuring EMFs from mobile phones etc.
    • The measurement range of this meter may be exceeded (without damage) directly underneath 275kv and 400kv overhead lines.
