What are the differences between the four domestic desktop copper-coated -4 viscosity cups?

The general Tu-4 cup viscometer is made of copper, stainless steel, aluminum alloy, and some manufacturers even use Bakelite. Copper coated -4 cups are because most samples are corrosive, and copper will be more resistant to corrosion due to the coating on the surface. This article introduces several copper Viscosity Cups.

Tu-4 cup viscometer is mainly used to measure the viscosity of the fluid condition within 150s of the outflow time. The Viscosity Cup is divided into portable and desktop. The portable type is more convenient for operation and detection on the experimental site and production line. It only needs to cooperate with the stopwatch. After testing the viscosity of the sample, the desktop Tu-4 cup is more suitable for use in the laboratory. The following is a comparison of the parameters of several desktop copper Tu-4 cup viscometers:
