Hardness tester TH700 digital Vivtorinox hardness
Vivtorinox hardness is four pyramid indentation unitaverage pressure area bear the representation of thehardness value.
In the test force rules, the opposite angle is 136 ° four pyramid diamond indenter is pressed onto the surface,and maintain the required time, and then remove the test force. So, on the surface of a square cone extrudingindentation indentation measurement, average length ofthe two diagonal, calculate the area of indentation, thehardness value.
Can be achieved from soft to hard on various materialsfor calibration of continuous hardness. For example:
▲ is widely used in the testing of metal structure,including small parts, sheet metal, wire, foil, thinhardened layer and plating.
▲ can also be used for testing large test force cannottest such as glass, jewelry and ceramic materials.
▲ can follow the metal structure, test induction hardening or carbide materials such as internal hardness
▲ test force automatic loading, unloading, maintain.
▲ digital computing hardness value without checking table conversion: the indentation diameter and loadingcapacity of keyboard input, display direct readout hardness value.
