Fast & Precise Dielectric Measurements


Download Product Flyer (PDF, 1.0 MB)

This precision dielectric measurement system is designed to cover the 5 – 50 GHz frequency range with a single open-ended coaxial dielectric probe; with the DAK1.2E probe, the range is extended to 67 GHz. The system uses advanced algorithms and novel hardware to measure the dielectric properties of liquids, solids, and semi-solids over a broad range of parameters. The measurement method is fast and non-destructive to the material under test.

  • Characterization of materials for the electronics, chemical, food, and medical industries.
  • Measurement at high frequencies with excellent precision; broad frequency range coverage enables measurement of dielectric relaxation in a variety of materials.
