Automatic Engine Oil Apparent Viscosity Tester (CCS)

The Automatic Engine Oil Apparent Viscosity Tester (CCS) is a high-precision laboratory instrument designed to measure the apparent dynamic viscosity of engine oils at low temperatures using the Cold Cranking Simulator (CCS) method. Built in accordance with GB/T 6538 and ASTM D5293, the system accurately simulates engine cold-start conditions, enabling reliable evaluation of lubricant performance under high shear and low-temperature environments.

By integrating mechanical systems, optical-electronic sensing, and intelligent software control, the CCS viscosity tester delivers stable temperature control, automated operation, and consistent test results. Its compact, all-in-one design with touchscreen interface and multilingual support makes it suitable for global laboratories, R&D centers, and quality control applications.
