Suitable for measuring the drying time of surface coatings such as paints and coatings to ensure the surface quality of coatings. The motor drives the lever of the spherical contact to draw a circle at a certain speed under a fixed load. Calculate the drying time of the paint film d on the location where the trajectory disappears. Calculate the drying time using the following formula: distance=velocity x time.
