The benchtop hardness tester has good reliability, operability, and intuitiveness. It relies on magnetic force to adsorb the benchtop hardness tester on the surface of the steel without supporting the sample. If you want to continue to understand, then you can continue to look down.

What are the points of attention when using?

1. Wipe the top surface of the benchtop hardness tester lead screw and the upper and lower ends of the worktable, and place the worktable on the lead screw table.


2. Wipe the supporting surface of the benchtop hardness tester and place it on the workbench. Rotate the handwheel to slowly raise the workbench and lift the indenter until the small pointer points to the red dot and the large pointer rotates 3 times vertically upwards;


3. Rotate the indicator shell to make the long engraved line between C and B align with the large pointer;


4. Pull the loading handle to apply the main test force, and the large pointer of the indicator rotates counterclockwise;


5. When the rotation of the indicator needle of the benchtop hardness tester stops, the unloading handle can be pushed back to remove the main test force;


6. Read the corresponding scale on the indicator;


7. Turn the handwheel to lower the test piece, then move the test piece, and perform a new test according to the above steps (2)-(6). The Vickers hardness tester needs to be careful during the test and use, and test several times.


8. After the test, cover the machine with a dust cover.


What are the characteristics?

1. The test principle and accuracy of benchtop hardness tester conform to the standards GB/T230, ISO6508, and ASTM E110, and the error is not more than 1.5HR after testing by China Metrology Institute.


2. The test is fast, easy, and non-destructive. The Vickers hardness tester also has this feature.


3. The benchtop hardness tester is convenient to read, with good repeatability and high accuracy.


4. Equipped with a magnifying glass with light to ensure convenient reading when used in a dark place in the workshop.


5. It can test flat workpieces and curved workpieces with curvature from Φ50mm to infinity.


6. It is used to accurately test steel plates, steel pipes, shafts, molds, large forgings, and various large and medium-sized heat-treated parts, surface hardening, and parts on assembly equipment, especially suitable for testing the hardness of welds and heat-affected zones.


How does it work?

How does it work?

When HB>450 or the sample is too small, the Brinell hardness test cannot be used and the benchtop hardness tester is used instead. Under the specified conditions, press the indenter (diamond cone, steel ball, or cemented carbide ball) into the sample surface in 2 steps. After the main test force is removed, the residual depth h of the indentation is measured under the initial test force. The residual depth h of the indentation represents the level of hardness.


The indentation depth corresponding to each benchtop hardness unit is 0.002mm for benchtop hardness and 0.001mm for surface benchtop hardness. The shallower the indentation, the higher the hardness. The benchtop hardness tester test is divided into two types, one is the ordinary benchtop hardness tester test, and the other is the surface benchtop hardness tester test.


EBPU Electromechanical Equipment (Zhejiang) Co., Ltd. developed the benchtop hardness tester. If you need a benchtop hardness tester, we believe our products will satisfy you. Because we have carried out various inspections before leaving the factory to ensure high quality.
