The D-2 is an advanced pocketable hardness tester distinguished by its high accuracy, wide measuring range, simplicity of operation & above all it is a really portable instrument operating on three pencil cells of size AA. It is suitable for testing the hardness of many materials & finds applications for hardness testing in many areas of industry.
Measuring Method : The measuring principle is based on absorption of kinetic energy & its relation in conventional scales of hardness. This is achieved with help of the probe, wherein a small body with a hard tip is propelled against the test surface by a spring & latch arrangement. The motion of body is the measure of its kinetic energy. The instrument converts the signal of absorbed energy in to a chosen scale of conventional hardness.
