Portable Hardness Tester Guide


Let's take a look at the following small series, the operating guide of the portable hardness tester


(1) The object to be inspected should be placed on the ground, and it must be absolutely stable. There must be no sloshing. The detected position must not be suspended. If necessary, support blocks should be added.


(2) Open the hardness tester → material setting of the object → hardness value setting (HRC\HRB\HB) → hardness detection direction setting → start hardness test;


(3) Press the impact device on the surface to be tested and press it down. After 1 s, press the small cylinder protruding above the hardness tester. The hardness value will be automatically displayed. In this process, the operator must put the impact device. Stable, the direction should also be perpendicular to the measured surface;


(4) At least 3 points should be tested for each test site. The distance between the two test points should be ≥3mm. After the test, take the average value as the hardness of the part, record it, and then go to the next part to test;


(5) The test result is compared with the requirements of the object, and the requirements are qualified and transferred to the next process; if it is unqualified, it is transferred to the isolation zone and the test result is recorded.
