Abstract

Probes are provided with caps, the caps comprise rolling bearing elements so that the probes can be slid along a surface to be measured, without damaging the surface or wearing away the tip of the probe or a sacrificial cap. The rolling bearing elements can be arranged in a ring around the probe tip, with the plane of the foremost edges of the rolling bearing elements a predetermined distance from the probe tip. The caps can comprise a housing with a grip, to encourage users to grip the cap, which comprises the rolling bearing elements, rather than the probe.
