Redefining EMF Monitoring – Professional Tools for Modern Safety
The Microrad NHT 3DL EMF Meter is a high-performance analyser tailored for evaluating electromagnetic field exposure in line with EU Directive 2013/35/EU. Developed for accuracy and ease of use, the system supports 5G detection and ongoing workplace compliance.
This versatile device functions as both a portable meter and a fixed monitoring unit, delivering repeatable results you can trust in demanding technical environments.


NHT 3DL – Advanced EMF Analyser
Designed for engineers and safety professionals, the NHT 3DL includes a responsive touchscreen interface, Wi-Fi and GPS integration, and now stores over 1 million measurements via removable memory. With a robust 24-hour battery life, it’s equally effective on-site or in fixed locations.
Its selectable frequency modes and fast-response sensors make it ideal for 5G signal tracking, radar sources, and high-resolution field diagnostics.

EMF Probes for Targeted Measurement
Microrad probes support specific applications, with field and frequency specialisation:
- Electric Field (E) – Up to 40 GHz measurement
- Magnetic Field (H) – Static and low-frequency detection
- Broadband (B) – Comprehensive frequency coverage
- Combined Probes – E, H, and B fields in one unit (e.g., 33N / 33P)
- ER Series – Radar and pulsed field optimised
All probe types are automatically recognised and calibrated when connected to the meter.
