The wet film wheel is highly precise and easy to use. It consists of three wheels, the diameter of the center wheel is small, and the diameter of the two sides is larger. Roll the wet film wheel along the wet film, the center wheel will always touch the film. The scale of the contact point is the wet film thickness.
Wet film wheel accuracy: Within the recommended range listed in the catalog and the table below, the machining tolerance of all Jelly wet film thickness gauges is 2.5% over the entire range. For best results, try to avoid readings outside the recommended range. Test conditions may adversely affect the maximum achievable accuracy for any given application. Factors that affect the accuracy of readings include, but are not limited to: surface tension and flow characteristics of the coating being measured, humidity and hardness of the substrate.Measuring range (um) To : 0-200um Scale value (um) To : 10um Net weight (g) :170g.
