The KDND-303A Automatic Kinematic Viscosity Tester is a precision instrument designed to measure the kinematic viscosity of petroleum products according to GB/T265-1988. It uses fuzzy PID temperature control with ±0.02°C accuracy, supporting multiple standard temperature points (20°C, 40°C, 60°C, 80°C, 100°C). Equipped with 4 test holes for simultaneous measurement using glass capillary viscometers, it automatically processes timing results to calculate kinematic viscosity. The touchscreen interface, data storage (up to 2000 records), and built-in thermal printer make it ideal for laboratory testing and quality control.
