Model 435

Gashes and mars are not nice to look at, especially not 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 Cadillac. The mar is often from a small cause but can leave a big mess! Metal marking is another type of mar. Here, the culprits are small metal particles of coins or similar which "rub off", thereby leaving ugly scratches on the surface. Previously you could "inspect" a surface only with your fingernails. Now for the first time, the Model 435 Mar tester enables you to specifically define the behaviour of coating surfaces with an exact test value.

Scope of delivery:

• Mar Tester according to Oesterle, Model 435
• 3 test discs (duroplast, copper, steel)
• 3 force springs
• Case

NEW - ERICHSEN SmartPen - The new generation of mobile scratch hardness testing

For the hardness measurement of surfaces, there are our since many years well-proven hardness test pencils, models 318 and 318 S as well as models 435 and 435 S, already well established across the branches. With these test devices, the degrees of hardness of paint films, plastic coatings, etc. can be determined, named, documented and communicated in numerical values. No matter whether on a flat or curved surface, small or large, the instrument is always ready for use and, because of it’s small size, easy transportable.With the ERICHSEN SmartPen, a modular hardness test pencil with digital test force setting and display (resolution 0.05 N) is now available.
