Automatic Kinematic Viscosity Tester
Introduction
The Automatic Kinematic Viscosity Tester is designed for accurate determination of kinematic viscosity of petroleum products and lubricating oils in compliance with GB/T 265, GB/T 11137, ISO 3104, ASTM D445, and ASTM D446. Featuring a dual-bath design with independent temperature control, it enables simultaneous testing at different temperatures. Fully automated operation with infrared detection ensures high accuracy, efficiency, and reliable performance for laboratory and quality control applications.
Application
The instrument features a dual-bath design, with independent temperature control and separate measurement for each bath, enabling testing at multiple temperature points and eliminating the long waiting times typical of traditional single-bath systems.
