1) Investigations had been processed by comparing parameter for sclerometer of different shape of top, relatively movement velocity of the sclerometer and the material and the scratching depth.

2) The method that realizes data communication between hand sclerometer and computer with VB are introduced. Further data processing will be done.

3) The surface hardness of rubber object mounted on the equipment can also be tested by holding the head of the sclerometer in hand.

4) In this paper, large alloy iron parts and low-alloy steel parts after surface heat treatment, used in the diesel engine ,(http:///sclerometer.html) were tested and compared. By Leeb hardness sclerometer.

5) Use the SEM observe the metallographic, Use the Micro sclerometer measure the hardness of the coating.

6) The microstructure and properties of high manganese steel under the conditions of different rolling load were analyzed and studied through the OM, TEM and HD-187.5 sclerometer.

7) There are sound physical and chemical inspection equipment, optical microscope, universal test machine, desktop sclerometer .

8) Through field test, the reliability of metal material separation is affirmed by sclerometer testing repetition measurement. Moreover, ejection experiments are made in shooting range.

9) With instruments and the equipment and so on light microscope, llography microscope, micro sclerometer observe infiltrate the level the organization and the test infiltrate the level the performance.

10) The hardness, surface morphology and adhesion were analyzed and examined respectively by micro - sclerometer , scanning electron microscope and lever style omnipotence intension test machine.
