Coating Surface Abrasion Tester Microcomputer Controlled Surface
Performance Tester
Product Overview
The Coating Surface Abrasion Tester (QR-SUM) is a precision instrument used to evaluate the abrasion resistance of coating surfaces and green sand specimens under controlled
conditions. Abrasion resistance is a critical factor affecting the
durability, stability, and performance of molding materials in
casting processes.
The tester is equipped with microcomputer control, ensuring high accuracy, stable operation, and ease of use. With
adjustable testing pressure and accurate lap counting, the QR-SUM
provides reliable and repeatable results for both laboratory and
industrial applications.
