Benefits and limitations

As the probe used for testing is a constant size, the dimensions of the product to be tested can vary without considerably affecting the ability to compare results. A hemispherical or spherical probe may be used to imitate a finger pressing into a product and is preferable to a cylinder when the surface of the test sample may not always be presented as flat.
