Portable Leeb Hardness Tester LM500

Portable leeb hardness tester use the impact body of certain weight impacts against the testing surface under certain spring force, leeb hardness means the ratio of the impacting velocity and the rebounding velocity of the impact body when the spherically test tip is located 1 mm above the testing surface.

Features

Big data show,clear to see.

Can show three hardness scale at the same time,no need to change the scale.

Curve interface can show latest 10 impact data,it is more convenient to view the object uniformity.

Can store 11000groups data,each group includes 1~8 impact result.The average data will be displayed in three hardness scale,and also can show max,min,and max error of this group data,it is useful for people to analyze the results.
