Item Description

Features

• Compact, simple experimental unit for basic destructive tests
• Tensile tests, compression tests, Brinell hardness test

A solid understanding of the properties of materials is essential for technical and scientific professions. This knowledge helps select the suitable material, monitor production and processing and ensure the requirements in terms of a component. The materials test provides the necessary data in a reproducible and precisely quantified manner. The tensile test, bending test and hardness test are all part of classic destructive materials testing.

The range of experiments with Sci-tech Material Testing: 20KN Model MT156 covers tensile tests, compression tests and Brinell hardness tests in the base unit. Bending, shear and cupping tests can be conducted using the accessories. Disk and coil springs can also be tested. Optionally available are large compression plates for materials with a relatively low compressive strength or different geometry that require a larger contact surface (lab-own compression specimens).

The experimental unit has been developed specifically for experiments in small groups and is characterised by a clear design, simple operation and accessories that are easy to exchange.

The tensile specimens are clamped between the upper cross member and the crosshead. The compression specimens and hardness specimens are secured between the crosshead and lower cross member. The test force is generated by means of a hand-operated hydraulic system and displayed on a large force gauge with drag indicator. A dial gauge measures the elongation of the specimens.

The experimental unit can also be equipped with electronic force and displacement measurement. Using the Sci-Cal system for data acquisition, the measured values for force and displacement can be transferred to a PC where they can be analysed with the software.
