Test & Measurement
By Alison Dunn
Mitutoyo Canada Inc. recently released the new HM-200 Series Micro Vickers Hardness Testing Machines. HM-200 Series Micro Vickers Hardness Testers incorporate the latest optical systems for measuring indentation dimensions together with an electromagnetic test-force loading device – just two of many new, productivity-enhancing technologies designed into these machines. Depending on the model, Mitutoyo HM-200 Series Micro Vickers Hardness Testers are equipped with a touch panel controller and available CCD camera (System A) or with an included USB color mega- pixel vision system supported by AVPAK software for automatic indentation measurement (System B). HM-200 Series Micro Vickers Hardness Testers are equipped with an electro-magnetic test force device making it easy to precisely set the desired force, between 0.403 mN and 19610 mN (HM-220). Objective lenses provide a long working distance with six available MH Plan objectives. The 10X, 20X, 50X and 100X types are used for measuring indentations; the 2X and 5X facilitate widefield observation tasks. During test-site positioning, positioning information is displayed digitally; 25 X 25 mm or 50 X 50 mm stroke lengths are selectable. LED illumination offers a long service life with low power consumption.
