With our Fischer probes, youโ€™ll be prepared for any measurement challenge. Benefit from the largest probe portfolio on the market โ€“ even for the most demanding measurement tasks. Regardless of whether a standard, special, analog, or digital probe is needed for your measurement task, all probes are developed, manufactured, and tested in-house to the highest quality standards.

  • Widest probe portfolio on the market with over 100 standard probes
  • Numerous special probes for the most demanding measurement tasks
  • Different housing designs and properties depending on the application
  • Robust, wear-protected probe poles ensure long-term precise measurement results
  • Developed and produced in-house to meet the highest quality standards
  • Individual factory calibration of each probe ensures maximum accuracy and repeatability
  • Almost constant contact pressure even during manual measurement thanks to spring-loaded probe systems
  • Probes with integrated curvature compensation for reliable measurement on curved surfaces (amplitude-sensitive eddy current measurement method)
  • Probes with conductivity compensation to avoid the influence of different electrical conductivities (amplitude-sensitive eddy current measurement method)


  • Magnetic inductive probes: Non-magnetizable coatings on readily magnetizable base materials
  • Amplitude-sensitive eddy current probes: Non-magnetizable and electrically non-conductive coatings on electrically conductive, non-magnetizable base materials
  • Dual probes: Measurements on steel and non-ferrous metal
  • Phase-sensitive eddy current probes: Electrically conductive, including magnetizable coatings on many different base materials
  • Magnetic probes: Magnetizable coatings on non-magnetizable base materials and non-magnetizable coatings (especially thick metal layers) on readily magnetizable base materials
  • Conductivity probes: Measurement of specific electrical conductivity of nonferrous metals (e.g., aluminum alloys); confusion testing or indirect analysis of material properties (e.g., microstructure, purity, hardness) via conductivity readings
  • Duplex probes: Paint on galvanic zinc on steel, paint on hot-dip zinc on steel.
  • Ferrite probes: Ferrite content measurement and martensite content measurement on austenitic steels and duplex steels.


Solve every challenge precisely

Depending on the application, a probe must have specific properties to achieve a measurement result with the highest accuracy. The selection of the right probe, therefore, is essential for the quality of the measurement result. Thanks to decades of experience in many industries, we at Fischer offer a comprehensive range of high-quality measuring probes - both for coating thickness measurement and for materials testing. With our digital probes in combination with the devices of the DMP series, we offer you smart and future-proof connectivity via USB-C interface and Bluetooth in proven Fischer quality. Digital probes are available for the entire DMP series.

Features and criteria for probe selection

Examples of measurement considerations for selecting the optimal probe:

  • Size of the measuring area
  • Geometry of the test part or the measuring location
  • Surface condition of the test part
  • Combination of coating and base material
  • Thickness of coating and base material
  • Layer hardness
  • Manual or automated measurement
  • Ambient conditions, e.g. wetness
