Kappa creep testing machines

Kappa creep testing machines

Versatile high-precision creep testing machines for maximum cost-effectiveness.

  • Test frame with four steel columns for high lateral and axial stiffness.
  • Top-quality components include testXpert® II testing software and testControl measurement and control electronics.
  • The success of testXpert® II is based on more than 80 years’ materials testing experience and over 10,000 successful testXpert® installations worldwide.
  • testControl features intelligent sensor technology which recognizes & calibrates all connected sensors, including their defined force limits.
  • The Kappa range focuses on the key requirements of creep testing: load, temperature, strain and data security.
