Two fundamental criteria for a good test are repeatability and resolution for comparision between results. In many cases, where sample hardness/softness is required, a ball probe can provide both repeatability and resolution. The principle of the ball probe is that uniform compression force is distributed at a normal angle to the surface area of the ball. This gives an averaging effect over the local area being tested.
Probes are available in a variety of imperial and metric ball diameters:

Applications
Ball probes are invaluable for performing a wide variety of texture analysis tests. They are used in many applications where specimen hardness or softness is required.
They are ideal for testing fruit, vegetables and confectionery products. For specimens where the application requires the product to flow, for example cream cheese being squeezed from a tube, gels, pastes etc., it is possible to contain a sample in a container and penetrate the sample with the ball probe.
