Very many aspects apply to selection of the best-suited penetrators.

In general and as an initial approximation, we can state the following: the harder and more solid the material to be measured, the more pointed and needle-like the penetrator should be.

Due to their larger penetration cross-sectional area, tapered penetrators compensate highly for inhomogeneities in the material to be measured so that the measurement results generally show less dispersion than is the case if test needles are used.
