Available in four scale ranges, the Elcometer 155 is designed to measure uncured powder coating film thickness. This enables the application system to be set up and fine tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray.

Place the comb into the powder and draw the comb towards you. The measurement points (or teeth) are pointed and allow the powder to flow around them. The thickness of the powder lies between the biggest value where a drag mark is visible and the smallest value where a drag mark has not been produced.

Note: The thickness of a coating prior to cure is not necessarily the same value after curing. The powder comb is only suitable as a guide only.
