Probes - overview

The determination of the right probe is dependent on many factors such as:

• combination of coating material and base material
• the thickness of the layer and the base material
• the size of the measuring surface
• the geometry of the measuring object or
• the surface condition of the measurement object

Based on the different measurement principles we offer a variety of probe types:

• F-probes (ferromagnetic - blue spout) using the magnetic-inductive measuring method (DIN EN ISO 2808/2178 and ASTM B499) for measurements on magnetic base materials, such as iron and steel.
  
  
• N-probes (non-ferromagnetic - yellow spout) using the eddy current method (DIN EN ISO 2808/2360 and ASTM D1400) for measurement on non-magnetic electrically conductive basis materials such as aluminum, zinc, copper etc.
  
  
• FN-probes (combination probes - green spout), which are suitable for measurements on magnetic and non-magnetic base materials such as iron/steel and non-ferrous metals. The suitable measurement principle for the base material is selected automatically.
