Testequip  offer Linear Tester 249 that is suitable for surface testing. The new Linear Tester 249 is a multi-functional test instrument and can conduct several tests. The Linear Tester 249 offers the following testing:

Scratch tests: Tests can be done by single stroke, adjustable test force, pre-selected test speeds and pre-set displacement by a respective crank. The universal adapter allows the use of either a customer’s individual tools or tools according to standards.

Crosshatch cuts by single stroke, adjustable test force, pre-selected test speeds, pre-set displacement by a respective crank. The positioning of the cut distances made by manual lateral aligning of the specimen is supported by a ruler mounted on the sledge. Abrasion test: This test is done with pre-selectable amount of double strokes, adjustable test force and test speeds. To fix the abrasive media, a round and a rectangular adapter unit are available.

Solvent resistance and wipe test: ‘MEK Test’ (resistance against the solvent Methylethylceton) is done with pre-selectable amount of double strokes, adjustable test force and test speed. A replaceable special felt inset rubs cyclically onto the surface. The special felt is imbued with different liquids (solvents, oil, brake fluid, synthetic sweat and cleaning agents) and allows a statement to the resistance of the tested surface against the respective liquid.

In most of the laboratories, these tests are effected manually and are influenced by the particular person. The Linear Tester 249 protects from deviation and ensures the comparability of the test results as well as the repeatability of the test procedure. It can remove the graffiti simulation on a coated surface in the Research and Development department.
