The Handy Hardness Tester（SONOHARD）model SH-22 completely diﬀers from conventionaltesters which measure sizes of indentations on test samples using microscopes. SH-22
applies a diamond indenter equipped on a vibrating rod that presses on a test surface at
a ﬁxed force and then measures the hardness by ﬂuctuation of ultrasonic vibration.
Diamond indentor
When the vibration rod is applied to a softer surface object of identicalmaterial at a ﬁxed force, it makes a deeper indentation and isconstrained. Due to this, the resonance frequency highly increases.
Conversely, vibration rod is less constrained when it applied on hardobject surface and resonance frequency do less. Hardness value canbe calculated using the correlation between the frequency changes andhardnesses.
