FEATURES

* The Sand Mould Surface Hardness Tester is used to measure the surface hardness of the sand mould/core of the wet

mold and provide technical parameters for the formulation of the molding process.

* 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/corein manual or mechanical low and

medium pressure molding.

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

* The unit of type B hardness tester for sand mold surface is (g/mm ), but it is customary to use hardness H(A/B/C) I 2

nstead of unit. Because their values are elated and consistent, the corresponding hardness value is also large when the

unit value is large (g/mm2 )

* Low voltage indicator.

* Digital display gives exact reading with no guessing or errors.

* Can communicate with PC for recording, printing and analysing by the

optional software and cable for RS232C interface.

* Automatic power off to conserve power.
