Digital Touch Screen Hardness Rockwell Tester With Menu Structure

Digital Large Touch Screen Hardness Rockwell Tester With A Newly-Designed Displaying And The Menu Structure

The Rockwell Hardness Tester is equipped with a newly-designed large displaying and the menu structure equipped touch screen, easy operation and testing. The typical feature of present hardness tester is to test the hardness value reliably and accurately.

The errors of hardness values can be revised by pressing input keys; therefore, it enables the hardness values measured more precisely to meet the needs of test requirements.

Maintenance of the hardness tester and the precautions

1, tester is rarely used, the several tests should be carried out to make the tester stable and then carry out the necessary tests.

2, During the hardness test, when the loading and unloading of the test force or the keep of the dwell time is being carried out, it is prohibited to turning the load changing hand wheel.

3, The hardness block should be used only on the working plane with the distance of the two neighboring indentations and of the center of the indentations to their edges are not inferior 3mm. The life time of the blocks is 2 years.

4, During the transportation of the tester, the tester should be fixed with long poles, with the weights and the hanging rod discharged. Disconnect the power source before the weights and the hanging rod are taken out.

5, Keep the tester clean and cover the tester after the use, lubricate the hardness blocks and ball indenters with the grease.

6, Carry out periodic control of the tester, at least once a year in order to assure the correct operation of the tester.

7, The treatment of the common malfunctions of the tester. When the test is in the un-working state, please contact after-sales services from the factory.
