In China, capillary viscometer method is often used to test the kinematic viscosity of organic heat carriers. This method is manually tested and requires cleaning with acetone or petroleum ether, which is easy to cause environmental pollution. In this study, capillary viscometer method and stabinger viscometer method were used to test samples and compare the results. Through data analysis, it was proved that stabinger viscometer method has the advantages of high efficiency, green and environmental protection, and can be applied to accurately determine the kinematic viscosity of organic heat carriers.
