CETR offers a wide range of solutions to meet your coating and thin films testing, research and analysis needs.

If you wish to perform your own tests, CETR manufactures and sells the world’s most advanced testers, backed by a full warranty, outstanding customer service, on-site installation and in-depth training.

If you would like testing performed for you, CETR lab performs a wide range of tests to meet your testing needs. Strict confidentiality of your data is always guaranteed.

Our single-platform, multiple-configurations fully-computerized testers of the unique acclaimed modular design can perform practically all common mechanical and tribological tests of thin and thick coatings. This versatility has made them the most widely used tester in the world.

The tool comes with advanced options like inline imaging, which allows the tested sample to automatically move from under the tip to the integrated AFM or 3D profiler.

Some of the typical tests routinely run on the CETR testers for coatings are:

  • Scratch adhesion
  • Tape peel adhesion
  • Nano indentation and nano scratch
  • Micro indentation and micro scratch
  • Youngs modulus and stiffness
  • Friction coefficient
  • Nano and micro wear
  • Wear resistance
  • Scratch Hardness
