Mitutoyo America’s HM-200 series micro Vickers hardness testing machines feature productivity-enhancing technologies such as optical systems for measuring indentation dimensions and an electromagnetic test-force loading device.
The System A model features touch-panel controllers and is available with a CCD camera, while the System B model features a USB color megapixel vision system that is supported by AVPAK software for automatic indentation measurement.
An electro-magnetic test force device is designed to ease setting the desired force between 0.403 mN and 19,610 mN (HM-220). Objective lenses provide a long working distance with six available MH Plan objectives. The 10×, 20×, 50× and 100× types are used for measuring indentations, and the 2× and 5× types facilitate wide-field observation tasks. Positioning information is displayed digitally during test-site positioning, and 25- × 25-mm or 50- × 50-mm stroke lengths are selectable. LED illumination provides increased service life with low power consumption.
A motorized turret mechanism automatically switches the position of indenter and objective lens via a touch probe in the System A model or via a PC running AVPAK software. Both models allow manual switching of indenter and lens.
