SCRATCH HARDNESS TESTER 430 P-I with motor-driven cutting table and positioning control as well as manually actuated loading force adjustment and manually actuated test panel rotation, incl. control plates for cuts of 25 mm/40 mm length, loading force 50 N (without test tip) Power supply: 230 V, 50/60 Hz

Purpose and Application :
The motor-driven SCRATCH HARDNESS TESTER 430 P is a universal testing instrument designed for carrying out a wide range of tests on varnished and plastic surfaces to determine their resistance to scratches and cuts. Single cuts, parallel cuts and - by turning the specimen by 90A - cross-cuts can be applied to test panels of various thicknesses.

The SCRATCH HARDNESS TESTER 430 P is particularly provided for adhesion tests using the cross hatch cut method (in accordance with all mostly required standards) and for specific plastics tests according with Opel (scratch resistance and writing effect). For these as well as for further tests numerous setting possibilities on the basic instrument and a large variety of test tools are available.
Using the SCRATCH HARDNESS TESTER 430 P, series testing can be conducted with much greater ease. The results of testing are reproducible and well-defined.
