Thickness Measuring Wheel

The thickness gauge wheel measures the thickness of materials such as coatings, films, and paper by using a roller that contacts the material surface, converting mechanical displacement into a thickness reading. It is used for on-site rapid inspections in industries such as coatings, plastics, and printing.
Selection
When selecting a thickness gauge, consider the measurement range matching the sample thickness, accuracy meeting process requirements, material suitability for the working environment, a simple and reliable calibration method, a structural design that facilitates handheld operation, and dimensions appropriate for the measurement location.
