Sand Mould Surface Hardness Tester AS-120S-A/B/C
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.
