High Accuracy Handheld Analog Pointer Tension Meter for Tension Testing

Effect of test load force: If the test load force increases, the measured hardness will decrease, and conversely, the hardness value will increase. The Brinell hardness will change with the change of load force. The compliance of the Brinell hardness test depends on the accuracy of the code removal, the accuracy of the load application device, and the correctness of the load application method. Practice has shown that the relative error of the hardness value is related to the relative error of the load. Therefore, to improve the measurement accuracy of hardness values, it is necessary to reduce load errors. For example, operators should operate according to the basic principles of Brinell hardness, and regularly inspect and calibrate the Brinell hardness tester. Tests should be conducted under the standard conditions of Brinell hardness testing.

Hardness tester is a special instrument used to measure the surface hardness of coatings. There are two types of hardness meters: desktop hardness meters and portable hardness meters. Desktop hardness meters are mainly used in laboratories, with the advantage of high accuracy. Portable hardness meters are used for installed mechanical or permanently assembled components, and are easy to carry. The portable hardness tester integrates portable hardness testers such as Leeb, Brinell, and Rockwell, and can achieve free conversion of seven different hardness values. This eliminates the need for manual searching of hardness tables for tedious procedures in the past, and realizes the truly intelligent and portable characteristics.
