EF-5.1 Tensile Tester


EF-5.1 Tensile Tester

The unit is designed to demonstrate the tensile strength of test pieces of different materials.

  • An Innovative hands on modular system designed to enable investigation and the understanding of engineering principles
  • Datalogging capability



The Armfield EF-5.1 Tensile Tester apparatus is an addition to the EF range of accessories for Engineering Fundamentals.

The unit is designed to demonstrate the tensile strength of test samples of different materials.

In addition to the destruction of a test specimen, the key relationship between force vs elongation can be easily determined and visualised by the students.
