PUSHEN ZHY Automatic Scratch meter

ZHY Automatic Scratch Meter

It is used to test the scratch resistance of metal surface coatings, such as coil paints, can inks, metallic paints, automotive surface coatings, etc.

It is also suitable for the evaluation of scratch resistance of single coat or composite coating of color-coated sheets.

The scratch resistance of the coating is evaluated by the maximum load of the spherical steel needle to cut the coating or not to scratch the coating at a certain weight.

During the test, a hemispherical needle with a diameter of 1 mm is used to slowly touch the surface to make a scratch about 10 cm long. 

Depending on the purpose of the test and the load loaded, different degrees of penetration can be observed, ranging from surface traces to effective penetration. 

The motor drives the sample to make gentle contact with the needle, which passes over the sample and stops automatically when it reaches the end point.

The contact between the scribe needle and the metal substrate is identified by a voltmeter, which shows that an electric current is passing through the sample when the coating of the sample is cut.
