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).
Portable and handy instrument especially designed for tests on enamel in accordance with DIN 51 155. Enables the user to carry out tests on site.
