Bench hardness testers are measuring devices employed to evaluate hardness by monitoring continuously load and depth of indenter sinking into the material. Measurements are carried out applying a fixed load for a known time on a indenter in contact with the sample.
Shape, size, material and mass of the indenter determine the hardness scale read by the instrument.
Bench hardness testers are recommended for metrological laboratories and every application that demands maximum accuracy and repeatability.
