Probe of the Month – August

Introducing the Fischer Probe FTD3.3

The Right Choice for Paint, Lacquer and Anodised Coatings.

  • What is it?                   

Contacting probe for non-destructive measurement of coating thickness

  • How does it work?

High-frequency eddy current method

  • To ISO specification?

ISO 2360

  • Measuring Range

0 – 800 μm         

  • What are the unique selling points?

 Automatic correction for the curvature of the coated sample that removes the need for frequent re-calibration

  • What are typical measuring applications

Thickness of anodic films and polymeric coatings on aluminium, brass, or copper and non-ferromagnetic substrates

  • What are the main markets

Aerospace, automotive, aluminium extrusions

  • Suitable Fischer instrument types

ISOSCOPE®, DUALSCOPE®, FISCHERSCOPE® MMS® PC2 with the module, PERMASCOPE®

The FTD3.3 contacting (tactile) probe used in conjunction with a handheld or bench mounted instrument from FISCHER makes it easy to measure coating thicknesses non-destructively. Using a high-frequency eddy current principle to ISO 2360, its unique automatic curvature correction removes the need for frequent re-calibration on curved surfaces. It is widely used to measure anodic film and polymeric coatings on aluminium in the aerospace, automotive, and aluminium extrusion industries.
