Wet Film Thickness Gauges with notches
Article No. 3507
Comb Gage 5-150 µm, stainless steel
Wet Film Thickness Gauge - hexagon in microns
- Made of stainless steel
- Measuring range: 5 - 150 µm (0.2 - 6 mils)
- Outer diameter: 58 mm
Features
Wet film comb gages also know as notch gages are formed on the edge of a piece of material so that each notch has a different clearance from the reference shoulders to its neighbors.
BYK-Gardner offers comb gages in many different materials, such as stainless steel, aluminum or plastic in a variety of shapes: square, rectangle or hexagon. Depending on your application single or dual scale combs in microns / mils are available.
Wet film measurement provides first opportunity to do a quick check of the coating and its application process
Simple low-cost device which is useful whan approximate values are satisfactory
Very useful for coating systems where the dry film thickness can only be measured destructively
Standards
Procedure
- For measuring, push the comb gage perpendicularly into the film using the measuring range that corresponds to the expected film thickness
- Remove the comb gage from the coating
- The wet film thickness will fall between the clearance of the shortest tab that is wet and the clearance of the next shortest dry tab
