This is a simple but effective method for determining the coating adhesion on a wide range of substrates. This adhesion tester is ideal for coatings on flat surfaces and is available with one of three different spacings; Each cross hatch gauge can be supplied separately or combined in a kit with a standardised brush and x10 magnifier.
Elcometer 501 Pencil Hardness Tester 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 501 has been designed to ensure that the cylindrical pencil lead is maintained at a constant angle of 45° and exerts a force of 7.5N (1.68lbF). The pencil lead, prepared beforehand using the special sharpener and abrasive paper, is inserted into the Elcometer 501
Elcometer 3092 Sclerometer Hardness Tester The Elcometer 3092 tests the hardness of a coating by moving a Tungsten Carbide Tip over the coating with predetermined force. The body of the instrument contains a cursor fitted with a screw lock and a round tip, compressed by one of the four springs corresponding to the four printed scales: Grey spring: 0-3N (0.671lbF) Red spring: 0-10N (2.248lbF) Blue spring: 0-20N (4.49lbF) Green spring: 0-30N (6.74lbF)
Elcometer 3086 Motorised Pencil Hardness Tester Traditional pencil hardness testers can be limited in their reproducibility and repeatability by two key factors; the uniformity of the carriage speed and the variation of the applied force by the user as the manual tester is moved across the coating. The Elcometer 3086 Motorised Pencil Hardness Tester, using the same test methods and principles as the Elcometer 501 Pencil Hardness Tester
