AFFRI Hardness Tester DM8 /DM2

Details

Automatic hardness tester for MICRO and MACRO Vickers and Knoop method, single or multiple indentations. DM8 series are microhardness testers with high
accuracy standards. Equipped with a motorized rotating turret with combined magnification lenses and indenters for reading and indenting. For micro and macro
Vickers and case depth test on all metals: Iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding,
cementation and hardfacing. Knoop test on ceramic and glass materials.

	SLOT ROTATING TURRET Horizontally rotating turret with four slots for magnification lenses and two for indenters. All optical microscope objectives can be pre-installed and combined with indenters for every Vickers and Knoop hardness scales. Optical objectives selection of 2.5x – 5x – 10x – 20x – 40x – 50x – 100x.
	DIGITAL EYEPIECE Really easy to use. Just spin the two lateral wheels of the eyepiece and match the reference lines with indent’s corners. Push the front button for automatic read of the diagonal. Spin the entire eyepiece and repeat the measure for the second diagonal. The result immediately appears on the display with updated statistics.
	X/Y MANUAL TABLE Manual XY table 100x100 mm with 10 μm step. This table is a perfect solution for not-daily multi indentation test cycles. The table allows manual CHD case depth tests and can be provided with digital micrometers for automatic CHD graph generation.
	X/Y MOTORIZED TABLE XY motorized table with an accuracy of +/- 0.5 μm steps, reference points for patterns indentations can be positioned precisely where they are required. The table allows automatic multi-indentation CHD test cycles on multiple samples with perfect positioning on the entire area, no matter the indentations amount.

SEMI SOFTWARE
The AFFRI Vickers measuring software has been studied to fulfill any client needs and to be accessible to every operator. This is a “SMART SOFTWARE” which results extremely easy to be used and can be customized to display only needed testing procedures.

AUTO SOFTWARE
Single or multiple samples in automatic cycle: Just map-out indentation traverses where they are required, set the load and press START, the hardness tester intelligently follows the predefined patterns, indents the sample, focuses when needed, measures, and generates data dynamically. The software is designed for an intuitive and simple use. With three easy steps, it provides added precision when positioning indents thanks to its integrated macroview technique and layout tools. By visualizing the complete sample or a single sample, traverses and/or patterns can now be mapped-out with unequaled precision.
