Features
- The surface hardness of sand mold is divided into three types
- Suitable for the surface hardness test of fine sand mold or core
- Manual or mechanical low and medium pressure molding
- Suitable for the surface hardness test of fine
- Coarse sand mold or core in manual or mechanical low
- Medium pressure molding
- Suitable for the surface hardness test of sand mold in high pressure
- The unit of type B hardness tester for sand mold surface is (g or mm2)
- But it is customary to use hardness H (A or B or 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 or mm2)
- With average calculate function
- Peak value deposit function
- Under-voltage alarm function
- Use USB data output to connect with PC
- Provide Bluetooth data output choice
