    Wet Thickness Gauge

    Overview Products Knowledge Standards Terms
    A wet film thickness gauge measures the thickness of wet films, such as coatings and inks, on substrates through mechanical contact or non-contact methods. The principle is based on the interaction between the probe and the surface of the wet film, allowing direct reading or calculation of the thickness value. It is used in printing and coating process control to ensure coating uniformity. Applications include on-site wet film thickness testing in areas such as paper coating and plastic film printing.
    Selection
    When selecting a wet film thickness gauge, it is essential to consider a measurement range that covers common wet film thicknesses, with accuracy meeting process requirements. Choose between contact or non-contact probes based on material characteristics. The operating environment determines the required protection rating, with laboratory types focusing on precision and portable types emphasizing field use. The gauge should be compatible with common substrate types and feature a simple and reliable calibration method.
