You use the kit to test the harness of a finish coating, like a paint or a ceramic coating for cars. Pencils have their own hardness scale which can be used to gauge the hardness of the coating. Its really more of a relative qualitative test than quantitative as you'd use this for sample/coupon testing identical coatings. There are more absolute, quantitative methods to measure various hardness characteristics (scratch, indentation, and rebound). Like you'd use the pencil kit on a factory floor to make sure each paint sample performs the same, the sample being a small area on the product or a plate that's painted the same way.
- 8note 3mo agothe pencil aspect is because its easy for a person to carry and take notes with? and you dont need to fit the car into a proper harness tester?
- wildzzz 2mo agoNo, these are expensive pencils that have high quality assurance to make sure the graphite is as hard as it's supposed to be. You use a jig to hold the pencil in a specific way each time. Don't think of it as a pencil, it's a kit of rods made from graduated compositions of graphite and clay. You could write with one but that's like making a PB&J with the NIST peanut butter, a waste of money.
