The KVL2000 Ubbelohde Viscometer is manufactured in compliance with various domestic and international testing standard methods that employ the Ubbelohde capillary tube method. It is primarily used to determine the molecular weight of organic polymer substances and the viscosity of other liquid samples. This instrument can directly calculate the kinematic viscosity value from the flow time of the liquid sample, or it can use the flow time to substitute into various standard formulas to calculate final intrinsic viscosity, K-value, molecular weight, and other results. Additionally, this instrument also meets the requirements of standards such as GB/T 265 "Determination of Kinematic Viscosity and Calculation of Dynamic Viscosity of Petroleum Products" and other capillary tube methods. Furthermore, the instrument can also serve as a high-precision cold bath for conducting other experiments. It features an intelligent measurement and control system, with touch-key settings for precise and automatic control of the test bath temperature.
