What is The Through-Diamond-Technique Method? While both methods – UCI- and Rebound – are successfully used in the field and solve many on-site hardness testing applications, there are limitations concerning the kind of material under test and its size and weight, respectively. Furthermore, because ... Leer más

What is Full-angle Leeb Hardness Tester? The full-angle Leeb hardness tester measures at any angle in accordance with the Leeb principle to calculate the hardness value, regardless of whether it is upward, downward or horizontal. The same measurement results are obtained for the same workpiece in ... Leer más

The Practical Application of TDT Hardness Testing The PC-based TDT system consists of a hand-held PC and the TDT probe. The interface between instrument and probe serves as power supply for the probe as well as connector for all control functions. The interface also feeds the BAS signal from the CCD ... Leer más

Hardness Test of Rebound Method Hardness testers using the Rebound method operate in a slightly different manner. Although the size of the test indentation generated is connected with the material hardness even in this case, it is indirectly measured via the loss of energy of a so-called impact body... Leer más
