The PCE-2000N hardness tester from PCE Instruments uses the Leeb rebound method. This is a dynamic hardness test procedure in which a standardized test body, usually a carbide ball, is struck on a test surface with defined impact energy. The impact of the carbide ball on the test surface causes a plastic deformation of the surface at the point of impact. This deformation results in a loss of energy, which is proportional to the workpiece hardness and can be determined by the ratio of rebound to impact velocity of the test body. This technology enables a compact design, which is why it is particularly suitable for the hardness meter. In contrast to static test procedures with heavy hardness testing machines, a mobile hardness tester can be used very flexibly in incoming or outgoing goods inspection, in production and generally in all areas where hardness has an influence on quality parameters. The hardness tester from PCE Instruments can measure six different hardness scales (HL, HV, HRA, HRC, HB, HV, HS) as well as ten different materials. As standard, the hardness measuring device is supplied with a impact device D, but other impact bodies (DC, DL, C, D+15, E, G) can also be connected optionally for special applications. In addition, the storage of data directly on a USB stick is possible, was this mobile hardness tester further extended the flexibility. Thanks to a very easy to read OLED display, a long standby time, a handy casing and a symbol-based menu navigation, the handling of the mobile hardness tester is extremely user-friendly.
