YFYIQI Sand Mould Surface Hardness Tester Portable Mould Hardness Tester Meter HB Unit For Fine Coarse Sand Mold/Core In Manual Mechanical Low Medium Pressure Molding
Features:
* 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.
* Under-voltage alarm function.
