For example, the torsional resistance of the material to the spherical indentor
was slightly lower than its resistance to the flat sphere shape indentor
at a lower axial load, but the rating switched at higher loads.
Instruments with a spherical indentor
and foot gave the smallest errors; the largest errors were associated with the durometer.
The A-Micro kit is comprised of a special probe containing the micro indentor
A spherically tipped indentor
is then applied under a constant "primary" load to the sample surface for five seconds.

In this indentation method, a conductive indentor
tip is pressed through a thin film of the material and into a conductive substrate while the instrument measures the gap distance and conductance simultaneously.
was set to move at a constant speed of 50 mm/min.
Hardness measurements were taken in the central area of each specimen and readings were recorded immediately after removal of the indentor
to minimise the effects of elastic recovery of polymers on the results.
not including the pileup around the indentation which varies in direction according to the shape of the three-cornered indentor
Most instruments used in the past have an indentor
that compresses the tissue while both force and tissue deformation are recorded simultaneously.
The microhardness of the condensates was measured on transverse sections of the specimens using a Polivar Met optical microscope fitted with an attachment for measuring hard-ness at a constant load on the indentor
Our results allow for the conversion between different hardness scales, not only between hardness scales of the same indentor
geometry, but those of different geometries as well.
The large clockwise rotations and displacements predicted by the indentor
model for Borneo are incompatible with palaeomagnetic evidence and there is no evidence that the major strike--slip faults of the Asian mainland reach Borneo.
In addition to an optical microscope, the system has an atomic force microscope (ATM) equipped with a specially designed probe to measure particle shapes, and a diamond compression indentor
whose tip is flattened using a focused ion beam (FIB) process to the extent that the tip is 1 micron in diameter, narrow enough to compress just a single particle at a time.
Vickers microhardness was measured using Matsuzawa microhardness tester using a diamond pyramid indentor
