Phase II Coating Hardness Tester PHT-995
The Phase II Coating Hardness Tester is engineered to determine the resistance of coatings to scratch effects on the surface. Utilizing the Wolff/Wilborn principle, this coating hardness testr conforms to ASTM D 3363-05.
Pencils of various known hardness are dragged over the coating surface at a fixed angle and fixed pressure. Beginning with the hardest lead, graduating softer, movements of .250" (6.5mm) will determine where the surface area is/is not being gouged or scratched.
Pencils can be changed easily via a knurled thumb screw on the side of the instrument.
