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.
