Electromagnetic field meter - broadband, selective and FFT analysis: SMP3 | Wavecontrol

The SMP3 is a professional electromagnetic field meter designed for EMF exposure assessment from 0 Hz to 60 GHz, depending on the connected field probe. It combines broadband measurement, frequency selective analysis up to 10 MHz and static field measurement in a single portable instrument.

The system is suitable for worker safety, regulatory compliance and technical field investigations in laboratories, industry, telecommunications, energy, railway, aeronautical, defence, automotive and medical environments.

With plug-and-play probe recognition, real-time graphical display, Weighted Peak Method, SQL data logging and optional fibre optic connectivity, the SMP3 provides a flexible platform for broadband and selective electromagnetic field measurements.

Why choose SMP3

The SMP3 is designed for teams that need a single, modular platform for comprehensive EMF exposure measurements. Its compatibility with a broad range of electric field, magnetic field and combined E&H probes allows the same instrument to cover applications from static fields and low-frequency exposure assessment to broadband RF measurements up to 60 GHz.

The instrument is particularly relevant for compliance-driven workflows thanks to Weighted Peak Method, real-time limit comparison, configurable averaging, scheduled measurements and high-capacity data logging. With automatic probe recognition, graphical real-time display, screenshot function and USB-C data transfer, the SMP3 supports both field measurements and structured reporting workflows.
