This largest aluminum fair in the Middle East attracts exhibitors and visitors in the related to the aluminum manufacturing industry from all over the world. At the show we will introduce our Webster hardness testers, portable Rockwell ... http://www.hardnesstesters.biz/blog/2009/03/tianxing-to-attend-aluminum-show-in-dubai/   The Ames Hardness Tester for Rockwell testing has been giving repeatable accurate measurements in large and small plants around the world for over 50 years. The light weight and portability of the Ames hardness tester saves time and money by providing Rockwell test results quickly, anywhere. Ames Portable Hardness Testers are ... http://www.hardnesstesters.biz/blog/2009/02/ames-portable-hardness-tester/ The hardness testing of plastics is most often measured by the Rockwell hardness test or Shore (durometer) hardness test. Both methods measure the resistance of the plastic toward indentation, thereby providing an empirical hardness value. These hardness values do not necessarily correlate to other properties or fundamental characteristics. Rockwell hardness ... http://www.hardnesstesters.biz/blog/2009/02/rockwell-hardness-testing-of-plastics/ The hardness of plastics is most commonly measured by the Shore (Durometer) test or Rockwell hardness test. Both methods measure the resistance of plastics toward indentation and provide an empirical hardness value that doesn't necessarily correlate well to other properties or fundamental characteristics. Shore Hardness, using either the Shore A ... http://www.hardnesstesters.biz/blog/2009/01/hardness-testing-of-plastics/ The Mohs hardness scale for minerals has been used since 1822. It simply consists of 10 minerals arranged in order from 1 to 10. Diamond is rated as the hardest and is indexed as 10; talc as the softest with index number 1. Each mineral in the scale will scratch ... http://www.hardnesstesters.biz/blog/2008/12/mohs-hardness-scale/ Designed to use forces from 10gf to 2kgf, an automatic micro Vickers hardness testing machine features motorised turret and load change mechanisms to speed and ease hardness testing. Indentec Hardness Testing Machines has recently launched the first British made fully automatic micro Vickers hardness testing machine. The new ZHV model is ... http://www.hardnesstesters.biz/blog/2008/11/hardness-testing-system-is-fully-automated-2/ For a Spanish manufacturer of stainless steel, the machine forms part of a robotic test cell that will work unattended for twenty four hours a day seven days a week. Using transfer mechanisms driven by signals from the software, the cell will check the dimensions, surface finish, hardness and tensile strength ... http://www.hardnesstesters.biz/blog/2008/11/robotic-hardness-tester-installed-in-spanish-mill2/ Believed to be the first robotic digital Vickers hardness testing machine, it has been installed in a Spanish stainless steel mill for checking prepared stainless steel specimens. Indentec believes it is the first to engineer a digital Vickers hardness testing machine for fully robotic operation. The Stourbridge Company has eliminated the human ... http://www.hardnesstesters.biz/blog/2008/11/robotic-hardness-tester-installed-in-spanish-mill1/ Its software also calculates hardness automatically from the indentation and provides an unequivocal read-out of the Rockwell number on an eye level display with no requirement for human interpretation. The benchtop machine carries out the Rockwell hardness test on an automatic cycle, a bar graph simulating the movement of the indenter and ... http://www.hardnesstesters.biz/blog/2008/11/measurement-of-hardness-is-consistent-on-cutters2/ The adoption of the Rockwell test has enhanced both accuracy and scope of hardness testing for Britain's leading manufacturer of commercial grass and hedge cutting equipment. Ludlow based McConnel, which commands 80 per cent of the UK market, has opted for the Rockwell method to overcome problems in reaching awkwardly located ... http://www.hardnesstesters.biz/blog/2008/11/measurement-of-hardness-is-consistent-on-cutters1/
