Tester digital pentru testarea duritatii Brinell, Rockwell, Vickers NOVOTEST TB-BRV-D
Digital Universal Hardness Tester with touch screen is a high-tech multi-purpose, and multi-functional hardness testing equipment, with LCD digital screen.
This hardness tester uses a multi-stage test load and different types of indenter to measure and determine the hardness value of tests products by Brinell, Rockwell and Vickers scales. The device can be used for hardness testing of both ferrous metals and non-ferrous metals, surface hardened steel, hardened steel, alloy steel, various QT and annealed steel, hardened steel sheet, also suitable for soft metals, surface treatment metals and chemical processing metals. The microscope is build in. Hardness tester provides the high sensitivity and accuracy of the load level, and the high accuracy of the measuring values.
