Narda ELT-400 Exposure Level Tester/Magnetic Field Meter

Description

This new generation ELT-400 greatly simplifies the assessment process. With the EXPOSURE STD (Shaped Time Domain) mode, the instrument achieves a new standard in the simple but reliable measurement of magnetic fields, whether straightforward or in complex field environments.

Time-consuming and easily-misinterpreted measurements with a spectrum analyzer or a scope are rendered obsolete. Detailed knowledge about the evaluation procedure, field waveform or frequency is no longer needed. The results are reliable and speed and ease of use are significantly improved over all traditional methods.

Features

  • Direct Evaluation of Field Exposure  - Compared to Major Standards (IEEE C95.6)
  • Automatic Exposure Evaluation for Various Waveforms
  • Eliminates the Overestimation that Can Occur with FFT-based Evaluation
  • Ultra-Wide Frequency Range (1 Hz to 400 kHz)
  • Wide Measurement Range (up to 80 mT, type-dependent)
  • Isotropic 100 cm2 and 3 cm2 Probe (complies with standards)
  • Three-Channel Scope Output
