It is used to determine the wet sand mould (core) surface hardness, for playing molding process to provide technical parameters. According to the size of the spring force and the stroke is the principle of linear relationship, the size of its stroke through a set of gear, the transmission of the rack by the surface pointer. The hardness of the surface of the sand B Type of unit is (g/mm2), but not in the habit
of units but with the hardness to say. Because their values are related and consistent, both large (g/mm2), the corresponding hardness value is also large.
Specifications:
1. Compression stroke: 2.50mm
2. Maximum load: 980g
3. Pressure load: 50g
4. Head shape and size: Ball R12.70
5. Accuracy: When the pointer is at any value, the pressure of the pressure head is allowed to be 5%. When the pointer is returned to the 0 position, the tolerance is 1 degrees.
6. Outline dimension: 90 * 55 * 28mm
