Patented design for micro-calotest with quantitative measurement of coating thickness

If you want to have further information or see exemplary test reports & specifications, please click here.


Thin films and coatings with a few nm to μm thickness are often applied on many products for the optimization of their mechanical properties and tribological performance.
Therefore, an accurate measurement with high resolution is essential for R&D, quality assurance and process optimization for many industrial applications. Thickness measurement is typically done with a combination of indentation and scratch tests, and they are mostly for thicker coatings in micrometer range.

Taperader®, is by far the only measurement instrument that provides a mobile, fast, in-situ solution for real-time analysis of surface coatings, e.g. soft coatings. Its unique design allows for a wide range of applications on either a lab sample or finished products.

Taperader® measures:
  • abrasion depth
  • thin coating thickness


  • loading system: providing a constant load
  • highly defined tape: for micro-grinding
  • Speed control system
  • Optical height profile measurement system: real-time documentation of abrasion depth in nm resolution
  • display: LCD graphical display
  • data acquisition and transmission software: built-in software with USB, Bluetooth functions
