A penetrating measuring apparatus (10) comprising: a stage (11) for mounting a sample to be tested, a probe (12) which extends at right angle to the stage (11) with an ultra-micro hardness indenter (20) in the end of the probe (12) nearest the stage (20), a carriage assembly (15) on which the probe (12) is mounted by elastic couplings (14a), (14b), (14c) and (14d) of known stiffnesss and an actuator (19) to drive the carriage (15) in a direction towards the stage (11). The probe is prevented from undergoing any but axial movements. First and Second measuring systems (16), (17) measure movement of the probe (12) relative to a known datum and the carriage (15) respectively. From the first measuring system (16) data is provided regarding actual penetration and the second measuring (17) system provides data indicating the force applied to the indenter. A control system for the inventive apparatus is also disclosed. |
