Mar Resistance Tester

Products Description:

Qualtech Products Industry Mar Resistance Tester is an Automatic Scratch Tester to determine the Mar Behavior and the Scratch Resistance of samples at the touch of a button.

The Mar Resistance and the Scratch Resistance of samples differs in the degree of the damage that may occur during the Mar & Scratch Test on the sample surface.

The Mar Resistance is the ability of samples to resist light scratching, the Scratch Resistance is the ability of samples to resist deeper and harsh scratching across the sample surface. Mar is primarily an optical issue caused by fine and visible scratches on sample surfaces which affect the appearance of sample surfaces, a Scratch is a deeper damage on sample surfaces which may damage the entire coating and go through the entire applied multi coating system.

This professional Automatic Mar & Scratch Tester automatically completes Mar & Scratch Tests and offers the newest microchip technology combined with a high performance motor, precision engineered mechanics, advanced sensors, a range of abrasive indenter in accordance with relevant test standards, a wide range of test loads in accordance with relevant test standards, user-friendly sample handling, high accuracy, high repeatability, reliable performance and an ergonomic design.

This Automatic Scratch Tester is the preferred test instrument to evaluate the mechanical properties of the base material for research and quality management.

In addition to the included standard test loads and abrasive indenter in accordance with the relevant test standards, this Automatic Mar Tester offers custom engineered test loads and abrasive indenter to best meet your requirements.

Please specify the required test standard when ordering.
