Graphite pencils of varying hardness values are often used for the evaluation of the hardness of a coating. In a typical test, the pencil is maintained at a constant angle of 45o to the surface and a force of 0-10 N is applied while moving the pencil. It is essential to maintain a constant moving speed for a reliable measurement. The digital pencil hardness tester HT200 is equipped with computer-controlled motor and therefore capable of precise and reliable measurements.
- Running mode: forward or backward
- Running time: 1-60 seconds adjustable
- Applicable force: 0-10 N
- Data recording starts two seconds after starting the tester as indicated by two beeps. The initial two seconds are
neglected due to typical large error at the initial stage.
- Three beeps can be heard 30 seconds after the tester stops, indicating that the test is ready for a new test.
