DIN 53505, ISO 868, ISO 7619 Pressure 180g Digital High Pressure Mould Wet Mould Surface Hardness Tester HT-6710C
General Application
The High Pressure 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.
Features
* HT-6710C 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 model HT-6710A: Suitable for the surface hardness test of
fine sand mold/core in manual or mechanical low and medium pressure
molding.
Type B model HT-6710B: Suitable for the surface hardness test of
fine and coarse sand mold/core in manual or mechanical low and
medium pressure molding.
Type C model HT-6710C: Suitable for the surface hardness test of
sand mold in high pressure molding.
* The unit of type C 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).
* Average calculate function included.
* Peak value deposit function included.
* Under-voltage alarm function included.
* Use USB data output to connect with PC.
* Provide Bluetooth data output choice.
