Description
Digital Universal Hardness Tester is a TOP high-tech multi-purpose, and multi-functional hardness testing equipment, with digital LCD touch screen.
This hardness tester uses different types of indenters and multi-stage test load for hardness testing of wide range of tested products in different scales: Brinell, Rockwell and Vickers.
Hardness tester provides the high sensitivity and accuracy of the load level, and the high accuracy of the measuring values. The machine has built-in high precision microscope with backlighting.
Hardness tester is supplied with a special table which allows user to measure the diameters of imprints without removing the sample. The hardness tester has special stand for the microscope, which significantly simplifies operating the device.
Besides manual testing platform, it is completely achieve automatic operation, including loading, unloading, hardness value directly display etc.
Hardness tester TB-BRV-D is one of the easiest device in operating and servicing, but at the same time it is universal and multi-functional instrument in its class. Touch screen and automatically testing system make operator’s work much more comfortable.
User can measure hardness in various scales and have no problems with hardness measurement in a wide range – from very soft materials up to some of the hardest materials.
