Simple, compact and easy to use Hardness Test Pencil. The estimated or known spring tension is set with the help of the slider. Holding the instrument upright and placing its point on the test surface one draws a 5 to 10 mm long line at a rate of approximately 10 mm/sec. The stylus should produce a scratch which is just visible to the naked eye. If the spring pressure is too high, the scratch is clearly visible; if too low, no scratch appears. The applied pressure, fixed by locking the slider is marked in Newtons. Three scales are engraved into the test pencil for the three pressure ranges: No.1: 0 - 3 N (blue marked) No.2: 0 - 10 N (red marked) No.3: 0 - 20 N (yellow marked).
