Pencil Hardness Tester
Pencil Hardness Tester

This instrument offers an easy method for the determination of film hardness for coating applied to a flat substrate. The pencil lead, prepared beforehand by rubbing it on fine abrasive paper(400),is maintained at an angle of 45º and pushed with uniform pressure onto the sample, either leaving a superficial trace or causing destruction down to the substrate. It complies with the requirements of ASTM D 3363, ISO 15184. 

 
Main Technical Parameters
Three points are touched on the tested surface (roller、pencil lead)
