PAINT AND COATING HARDNESS TESTER

Color and coating hardness tester

Application: It is a tool for testing the hardness and scratch resistance of coating materials such as coatings, lacquers, plastics, etc

Model:

1-Pencil hardness tester

2- Pen hardness tester: This tool is used with three types of springs

3-Pandoli hardness tester:

determination of hardness with KONIG and PERSOZ methods.

In both methods, according to the ISO15220 standard, the number of oscillations of the pendulum on the surface of the sample shows the hardness of the sample

Surface roughness meter or roughness test

Surface roughness meter or roughness test

Application: To determine the texture of the surface roughness, by determining the amount of vertical changes on the surface compared to the real smooth surface

Manufacturing company: Mitutoyo of Japan and NEURTEK of Spain and AMITTARI of Hong Kong

Model :

1-Sandblast roughness meter

2-Surface roughness gauge (Ra, Ry, Rz)

Roughness is a measure to determine the texture of the surface and it is determined by determining the amount of vertical changes on the surface compared to the actual smooth surface. If these changes are large, it has a rough surface, and if it is small, it is soft. Roughness plays an important role in determining the mutual effect of surfaces and by knowing it, many behaviors of mechanical components can be predicted. In the usual equipment for roughness measurement, which is known as roughness tester or roughness tester, contact method is used and a needle-like head moved on the surface according to the number of oscillations and maximum displacement can determine the surface roughness.
