Permittivity Probe: permittivity measurement of pure liquids and solvent mixtures

The permittivity probe 871 is measuring the relative permittivity (dielectric constant) of liquid samples by immersing the probe into the liquid and reading the relative permittivity on the display.

The probe is made of stainless steel, nylon and teflon and therefore has a high level of chemical resistance. Thus it can use for almost every solvent.

Benefits and key features

  • Measurement of the relative permittivity of solvents and water (1 to 200)
  • Main application: permittivity measurements of solvent-mixtures, mainly for a comprehensive characterization of liquid dispersions (e.g. to calculate the zeta potential)
  • accuracy: ± 2 %
  • easy handling
  • easy cleaning thanks to an open prode-design
  • easy calibration using a liquid with a known permittivity
