Scratch Hardness Testing

Scratch Hardness Tester TriForcePencil Model 293

The TriForcePencil 293 makes it easier to carry out testing based on Wolff-Wilborn method, while simultaneously ensuring compliance with the prescribed force and angle. The guide is easy to use and eliminates manual influences on the pressure force. The classic Wolff-Wilborn test originally takes place with a test weight of 750 g. Currently, however, the test load of 7.5 N has prevailed for this purpose. The weight block of the TriForcePencil 293 has three pencil guides which, according to their positioning, exercise the appropriate test force on the tip of the pencil according to the principle of leverage.
