QualiWAST-II Multifunction Scrub Abrasion and Washability Tester

The QualiWAST-II Multifunction Abrasion Scrub Tester is a robust tool for abrasion testing. With interchangeable abrasion heads, it can meet all testing standards for linear reciprocating abrasion, including wet abrasion scrub, sponge washability, scrub resistance, cleanability, dirt pickup resistance, MEK test, Rub test, and more.

Furthermore, this machine utilizes a touchscreen interface for operation, allowing users to directly set all required test parameters and monitor its status conveniently. It's incredibly easy and straightforward to operate.
