Universal Scratch Tester 413

Scratch tester for surfaces, extremely finely graduated (0.01 N steps), with various test tips.  All methods that can be used with the SCRATCH HARDNESS TESTER 413 are basically based on the same method: The sample is mounted on a rotating table (number of revolutions in the standard version: 5 min-1). The test tool is attached to a load arm with adjustable weight that allows the tool pressure to be adjusted to the sample (load range of 0 – 10 N in 0.1 N increments and load range of 0 – 1 N in 0.01 N increments). The resistance of the sample to this effect is assessed visually using the scratch track (refer to the operating instructions for details).
