Hi, welcome to visit !
The gauge may now be read to determine the wet film thickness The ends of the teeth or notches are visually examined some will be coated or wet and some will not be coated or wet The wet film thickness WFT of the coating lies between the values of the smallest uncoated dry tooth or notch and the largest coated wet tooth or notch
