Product Description:

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

This professional Automatic Mar Tester performs Mar Tests and Scratch Tests on Single-Layer Coatings, Multi-Layer Coatings and Sample Surfaces and integrates a large Sample Area suitable for a wide range of samples and sample sizes.

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

The Surface Hardness Test and the Mar Test is divided into two main categories:

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

This professional Automatic Mar Tester offers the newest microchip technology combined with a large LCD Display, comfortable Softtouch Buttons, a large Sample Area suitable for a wide range of samples and sample sizes, durable Styli made of high quality materials, precision engineered mechanics, a wide range of Test Loads, optional custom engineered Test Loads, user-friendly  application, user-friendly sample handling, high accuracy and high precision, an ergonomic design, reliable performance, longevity and much more.

The included Styli and the included Test Loads are designed and engineered in accordance with ASTM and IS test standards, optional custom engineered Styli and optional custom engineered Test Loads are available to best meet your sample test requirements.

This Automatic Mar Tester is designed and engineered in accordance with international test standards including:
