About this item

1.Unit HC

2.Peak value deposit function.

3.Under-voltage alarm function.

4.With average calculate function

5.Suitable for the surface hardness test of sand mold in high pressure molding. * The unit of type B hardness tester for sand mold surface is (g/mm2), but it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the corresponding hardness value is also large when the unit value is large (g/mm2).

Features:

It meets standards of DIN 53505, ISO 868, ISO 7619, ASTMD 2240, JISK7215.

The surface hardness of sand mold is divided into three types: A, B and C, The common model is type B, among them:

Type A: Suitable for the surface hardness test of fine sand mold/core in manual or mechanical low and medium pressure molding.

Type B: Suitable for the surface hardness test of fine and coarse sand mold/core in manual or mechanical low and medium pressure molding.

Type C: Suitable for the surface hardness test of sand mold in high pressure molding.

The unit of type B hardness tester for sand mold surface is (g/mm2), but it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the corresponding hardness value is also large when the unit value is large (g/mm2).

With average calculate function.

Peak value deposit function.
