Abstract
A durometer is provided. The durometer includes an indentor point for penetrating under pressure of an applied load a surface being tested for hardness. Also included is a load generator, which may be a hydraulic cylinder. A support structure is provided for suspending the durometer's indentor point therefrom. An articulation joint connects the indentor point to support structure. Due to the use of this articulation joint, this invention avoids the deleterious effects generally accompanying transmission of moment from the support structure to the indentor point.
