Electromagnetic Field Monitoring – The New Standard in Safety Compliance
The Microrad NHT 3DL EMF Meter is a cutting-edge instrument for measuring electromagnetic fields in accordance with European Directive 2013/35/EU. This high-performance analyser is designed for precision, speed, and flexibility in complex monitoring scenarios — including 5G signal detection.
Whether used as a handheld instrument or in fixed monitoring applications, the NHT 3DL delivers accurate, reliable, and traceable results to manage individual exposure and demonstrate regulatory compliance in occupational environments.
NHT 3DL – EMF Monitoring Meter
Designed for use in demanding environments, the NHT 3DL combines touchscreen functionality, Wi-Fi and GPS connectivity, and now uses a memory card, capable of storing over 1 million measurements – all with a 24-hour operational battery life. The unit can be used portably or as a fixed monitoring solution. With selectable frequency modes and highly responsive sensors, it is ideal for detecting dynamic fields such as 5G signals or industrial radar sources.
Its intuitive interface and comprehensive software make the NHT 3DL easy to use for quick diagnostics and detailed evaluations alike.

High-Precision Measurement EMF Probes
Microrad probes enhance measurement accuracy by targeting specific field types and frequency ranges.
- Electric Field (E) Probes – Measure electric fields from 100KHz to 40GHz.
- Magnetic Field (H) Probes – Assess low-frequency and static magnetic fields.
- Broadband (B) Probes – Cover a wide range of frequencies.
- Combined Probes (33N & 33P) – Measure all three field types in one probe (DC to 400KHz).
- Series ER: Radar field probes with ultra-fast response
All probes are automatically detected and calibrated by the meter.
