Paint often becomes soiled especially near doorways, windows, and in work and play areas. Coated surfaces need to be tested for resistance to abrasion caused by a brush, sponge, or other means. The Wet Abrasion Scrub Tester can produce a repeatable, controlled condition to simulate everyday use or wear patterns.

        NT 526 Wet Abrasion Scrub Tester is the newest machine which is developed by Nitop . It can examine washability and related properties that affect the stain resistance of coatings. Detergent performance testing can also be determined in a reproducible manner.

        It accords with standards such as ASTM D2486、ASTM D 3450、ASTM D 4213、ASTMD 4828、DIN EN 11330、EN ISO 11998 etc.

Feature：

◆  Running speed can be set to meet requirements of different standards.

◆ With four-digit counter, start the machine and it will automatically be stopped when reaching set times.

◆ Compatible with a variety of abrasion pads to comply with different standards requirements, such as ISO, ASTM, DIN etc..

◆ Quickly and easily to load and unload testing samples and replacing abrasion head.

◆ Can work normally under different voltage and frequency

◆ With stable and uniform running speed because of Push-rod design

◆ Features two brush holders for side by side testing

◆ Long service life with hard and durable design

◆ The whole machine body is made ​​of anodized aluminum, having stable working status, repeatable test results, no exception even in the fastest speed of the stroke.

◆ With peristaltic pump design, control scrub mediumflow accurately.
