DAK - Dielectric Assessment Kit 

What are DAK and DAKS?

The Dielectric Assessment Kit (DAK) is ideal for all applications where high-precision dielectric parameter measurements (permittivity, conductivity, loss tangent) are required, including applications in the electronic, chemical, food, and medical industries. The dielectric probes are designed for fast, precise, non-destructive, and user-friendly measurements of liquids, solids and semi-solids over the 10 MHz – 67 GHz frequency range.

DAKS are the first-ever instrument to perform accurate, simple, and convenient dielectric measurements in the frequency range between 10 MHz – 14 GHz. The probe can be moved to the media under test to directly measure the dielectric parameters, thus eliminating phase distortions due to cable movements.

What are the Unique Features of DAK/DAKS?

Broad Frequency Range

The DAK technology extents the frequency range from 10 MHz – 67 GHz with only 3 probes and without compromise on uncertainty:

DAK-12: 10 MHz* – 3 GHz (*improved algorithms applied between 10 – 50 MHz)

DAK-3.5: 200 MHz – 20 GHz

DAK-1.2: 5 – 50 GHz

DAK-1.2E: 5 – 67 GHz 


DAKS Systems

DAKS-12: 10 MHz – 3 GHz w/ integrated Vector Reflectometer ()

DAKS-3.5: 200 MHz – 14 GHz w/ integrated Vector Reflectometer (R140, Copper Mountain Technologies)

High Precision DAK Probes

  • Manufuctured with maximum precision to minimize unwanted reflections.
  • Materials and shapes optimized to ensure excellent contact with the material under test; easy to clean to avoid cross contamination between probe and material; newly developed novel algorithms extend the frequency range of DAK probes down to 10 MHz (DAK-12) and up to 67 GHz (DAK-1.2E) with minimum uncertainty penalty.
  • Many innovations integrated into the shorting block for excellent system calibration, key for highly accurate and precise measurements. 

Easy To Use & Fast

  • Intuitive user-friendly DAK interface provides a wide range of graphical and numerical analyses.
  • Software developed by the IT'IS Foundation; advanced algorithms for fast, high-precision measurements; choice of complex permittivity parameters (ε', ε", σ, tanδ) plotted in a variety of data formats: linear, logarithmic, Smith charts, Cole-Cole plot, and tabular.
  • Robust data analysis suite enables data to be fit to analytical curves, compared with target parameters, with  tolerance and uncertainty ranges.

Wide Range of Dielectric Parameters

Precise measurements over a broad range of dielectric parameters:

  • εr: 1 – 200
  • tanδ min.: below 10−5
  • tanδ max.: greater than 10
