Tu-4 viscometer is mainly used to test the coating with an outflow time of less than 150s, and it can also be used to test semi-finished coatings and other related products with similar viscosity. In this issue, several domestic portable Tu-4 viscometers, including Jingke, Kexin, and domestic, are selected and compared. The specific parameters are compared in the table below. The material of the three is aluminum alloy, and the measurement time and capacity are different. Users can select the type according to their actual use.
