Shimadzu DUH-211S dynamic hardness tester with upright microscope and sample stage.
Gray-Little Hall, Room B105D

Features

  • Evaluation of Hardness and Material Parameters in Accordance with Standards (ISO 14577-1 Annex A)
  • Highly Precise Evaluation of Elastic Modulus
  • Low Test Force with Measurement Resolution of 0.196 μN
  • Ultra-Wide Test Force Range of 0.1 to 1,961 mN and test a variety of industrial materials, including rubber, plastics, and ceramics.
  • Specimen indentation depth can be measured in units of 0.0001 μm for depths up to 10 μm.
  • Record the relationship between the test force and the indentation depth. Test both the unload and load processes. Use the DUH-211S to perform cyclic load-unload tests and step load-unload tests.
  • Supports Vickers Hardness Test with function to measure the length of diagonals is provided as a standard feature. This function allows you to measure the hardness that corresponds only to plastic deformation, Vickers hardness, and Knoop hardness. Indenter tip shape correction is only available for the 115-degree triangular pyramid indenter.
  • Maximum microscope magnification is 500×
