This can be used to measure surface hardness of sand mould/ core of the wet mould. Three scales of A, B and C correspond to density of sand used.
A needle of specific size is hard pressed on to the sample, and the depth of penetration is measured to estimate the hardness of the sample. The unit of hardness tester for sand mold surface is (g/mm2), but it is customary to use hardness H(A/B/C) instead of unit, as they are related and consistent, the corresponding hardness value is also large when the unit value is large (g/mm2).
