Wet Sponge Pinhole Detector

The wet sponge pinhole detector reveals pinhole defects by wetting the sponge to contact the coating surface and utilizing the principle of water penetration. It is used to detect the continuity of coatings such as paints and inks, and is applied in quality control in the printing and plastic industries.
Selection
When selecting, consider the type of material to be tested and the coating thickness, ensuring compatibility with the instrument's voltage range and electrode size. Check the durability of the sponge material and the stability of the water supply system. Confirm safety certifications and ease of operation.
