The pencil lead, prepared beforehand using the special sharpener and abrasive paper, is inserted into the Elcometer 501 hardness tester and pushed over the smooth. The pencil lead, prepared beforehand using the special sharpener and abrasive paper, is inserted into the Elcometer 501 hardness tester and pushed over the smooth, flat coated surface.
501 Pencil Hardness Tester
The internal motor drives the unit at a constant, uniform speed across the coated surface, exerting a fixed, user determined force between 0. Note: For ASTM D 3363, the test is started using the hardest pencil and continued down the scale of hardness The pencil lead, prepared beforehand by using the special pencil sharpener and rubbing it on fine abrasive paper (400 grade), is maintained at an angle of 45° and pushed with uniform pressure on to the sample.
3086 Motorised Pencil Hardness Tester. The internal motor drives the unit at a constant, uniform speed across the coated surface, exerting a fixed, user determined force between 0. The pencil lead, prepared beforehand using the special sharpener and abrasive paper, is inserted into the Elcometer 501 hardness tester and pushed over the smooth, flat coated surface.
Motorised Pencil Hardness Tester, 280 Mm X 140 Mm X 240 Mm, Model Name. The pencil hardness test also referred to as the Wolff-Wilborn test, uses the varying hardness values of graphite pencils to evaluate a coating's hardness The Elcometer 3086 Motorised Pencil Hardness Tester, using the same test methods and principles as the Elcometer 501 Pencil Hardness Tester, removes both of these variables by being fully independent
