Wet Film Thickness Gauges
The Wet Film Thickness Gauges are made of a comb-shaped design with precision-cut gaps to determine the coating thickness by placing vertically onto a wet coated substrate. it is a corrosion-resistant stainless steel with a hole at the top corner so that a string（not supply）can be attached for hooking.
All Wet Film Thickness Gauges are machined by high precision CNC and with less than 3 micron devitation. They come standard with 10 gaps with inscriptions of the thickness at the side of each gap. It is recommended to replace a new gauge if there are chips, crack or uneven at the gap(s)of the gauge.
