ERICHSEN MEASURES HARDNESS AND MARS

New Erichsen scratch hardness testers 318/318S/318 C are used to measure the hardness of surface protective layers like paints and plastic coatings whether the surface is flat or curved.

Developed by Robert Bosch GmbH in Stuttgart and manufactured by ERICHSEN, the devices enable quick and easy quality control of surface protection layers, even during production. 

Gashes and mars are not nice to look at, especially on smooth, shiny paint surfaces. But they can occur quite quickly: fingernails can unintentionally scratch over a matt-polished table or a branch can grind across the beautiful paint of a car. Metal marking is another type of mar. Here, the culprits are small metal particles which "rub off", leaving ugly scratches on the surface. Previously you could "inspect" a surface only with your fingernails. Now, the Erichsen Model 435 Mar tester enables you to specifically define the behavior of coating surfaces with an exact test value.
