I. Precision instrument measures damage to surfaces not classified as ordinary wear.

Using interchangeable tools, the Taber Shear / Scratch Tester is used to measure the susceptibility of material surfaces to scratching, marring, shearing, gouging, scraping, engraving, and other similar physical damage not classified as ordinary wear.

II. Established tester can be used in diverse applications.

Useful in quality control as well as materials and product development, the applications are diverse. The Shear / Scratch Tester is ideal for evaluating adhesive qualities of surface coatings, detecting the lack of homogeneity in comparative materials, rating similar or competitive materials, or analyzing the effects of age under controlled environmental conditions.

III. Test a wide range of products.

Precision, calibrated weights provide a flexible testing range for a variety of products. The Shear / Scratch Tester can test rigid organic materials, adhesive coatings, paints, powder coatings, anodized materials, soft metals, synthetics, linoleum, laminates, plastics, glass, plus many others.
