The challenge

The tablet of  makeup powder must be sufficiently compact not to crumble during use, but not too hard because otherwise it would be difficult to apply.
Alternative techniques include the use of conventional Shore A durometers, with the destruction of the sample.

The solution

By means of an actuator  suitably mounted, a force of predefined value is applied to the surface of the tablet, leaving a slight print on the compressed powder.
In this way you get the advantage of a non-destructive test, which may also be applied in the production line.
