YFYIQI Digital Sand Mould Surface Hardness Tester Meter Gauge HA Unit with Testing Range 10 to 90H Average Calculate Function For Sand Mould Sand Core
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.
* Under-voltage alarm function.
