Digital Touch Screen Hardness Rockwell Tester With 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. The Technical Specifications: ♦ Initial test force: 98.07N (10Kg); Tolerance: ±2.0% ♦ Total test force: 588.4N (60Kg), 980.7N (100Kg), 1471N (150Kg),
Tolerance: 1.0% ♦ Indenter specifications: 120°Diamond Rockwell Indenter 1/16 (φ1.5875mm) ball indenter ♦ Power supply voltage: AC220V ±5%, 50-60Hz ♦ Time delayed control: 1-60seconds adjustable ♦ The Max. Height of the Specimen: 170mm ♦ The Distance (Indenter to the Body): 165mm ♦ Dimension of the Tester: 520×240×720mm (length ×width× height). ♦ Approx Net Weight of the Tester: 80Kg ♦ The Scales, Indenters, Test Force and Application Fields of the
Rockwell Hardness Tester (Table 1) ♦ The Tolerances of Display Value (The Commonly-Used Scale for the
Rockwell Hardness Tester are scales A, B, C) Technical Parameters:
Accessories (The Packing List):
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. Pictures:
