WP 300 Materials testing, 20kN



  • Compact, clear universal unit for basic experiments on materials testing
  • Tensile strength, compressive strength, bending, shear and cupping tests
  • Brinell hardness testing1
  • Recording of characteristic curves1
  • Can be extended with electronic data acquisition


Technical Description

This material tester is a benchtop unit for training purposes. Simple operation and robust construction make the unit suitable for student experiments. The test spectrum for the basis unit covers tensile tests, and also Brinell hardness testing. Using the accessories that are also available, additional bending, shear, cupping and compressive tests can be performed. PC data acquisition and evaluation is also possible.

The basic version of the unit does not require any additional sources of power. The test load is generated using a hand operated hydraulic system. The test load is displayed using a large gauge and a trailing pointer. The elongation of the test specimen is recorded via a mechanical gauge. The unit features a clear layout and the rapid changing of accessories.
