Multifunctional Washability Tester

The Multifunctional Washability Tester is a versatile abrasion testing instrument designed to evaluate the wear resistance of coatings, paints, and surfaces. By changing different friction heads, it meets all linear reciprocating abrasion test standards, including wet washability, sponge abrasion, stain resistance, solvent wipe resistance (alcohol, MEK), scouring pad resistance, and dry rubber abrasion. The instrument features full touchscreen operation, allowing operators to set test parameters directly and monitor the testing process in real time, ensuring convenience and ease of use.
