The growing presence of wireless systems—cell towers, Wi-Fi networks, industrial equipment, and electronic devices—makes it necessary to have reliable tools for quantifying exposure to electromagnetic fields. This electrosmog meter evaluates RF radiation levels over a wide frequency range, supporting technical diagnostics, audits, and safety validations.

It is a suitable solution for measurements on:

Cell phone towers
Wireless networks (Wi-Fi, DECT, GSM)
Microwave oven leakage detection
Evaluation of workplace and residential environments
Identification of RF sources (transmitters, hidden devices)

Field flux concept and measurement units

The most representative parameter in RF radiation is power density, which describes how much electromagnetic energy passes through a surface.

It is expressed in W/m² (watts per square meter)
It represents the energy flux per unit area
It allows exposure levels to be compared regardless of the type of source

This type of measurement is made with an isotropic electric field (E) sensor, typically triaxial (three-axis), which picks up the signal from all directions without having to orient the instrument manually.

The physical behavior follows an approximate propagation law:

The greater the distance from the source → the lower the power density
The decrease is generally proportional to the square of the distance (under ideal conditions)

Typical power density levels

The following table shows approximate reference values for common sources, useful for putting field measurements in context:

Source	Typical distance	Power density (W/m²)
Cell tower (urban)	50 – 200 m	0.001 – 0.1
Wi-Fi router	1 – 3 m	0.0001 – 0.01
Mobile phone (active use)	1 – 5 cm	0.1 – 10
Microwave oven (permissible leakage)	5 cm	< 5
Typical residential environment	—	< 0.01

Note: Permissible limits depend on the applicable standard (ICNIRP, FCC, etc.), but in many cases reference values on the order of 1 to 10 W/m² are considered for public exposure in certain frequency bands.

Instrument features

The meter is designed to cover a wide range of RF applications:

Frequency range: 50 MHz to 3.5 GHz
Triaxial isotropic sensor (3-dimensional measurement)
Direct measurement in multiple units (V/m, A/m, W/m²)
High sensitivity from 1 μW/m² to 30.93 W/m²
Wide dynamic range (≈75 dB)

This allows detection of both weak signals and high radiation levels.

Operating functions

The instrument includes functions that make field analysis easier:

Instantaneous, average, and maximum value readings
Configurable alarm with adjustable threshold
Internal memory for data logging
High-resolution digital display
Fast response time (~1 second)

Its portable design and stand-alone operation make it suitable for technical inspections without complex infrastructure.
