英國(guó)易高Elcometer 112和3236六角濕膜梳使用精密的六角不銹鋼材質(zhì)，經(jīng)久耐用，可重復(fù)使用，厚度范圍zui高可達(dá) 3000μm （120mils）.

這些六邊濕膜梳的大小各不相同，有24或36個(gè)測(cè)量值可選，根據(jù)型號(hào)不同，有增加的精確度可選.

使用濕膜梳

將濕膜梳垂直放置，接觸到基體。保持原地等待幾秒鐘，直到梳齒變濕。拿開(kāi)濕膜梳.

濕膜厚度在"含漆"或"濕"齒zui大值和"不含漆"或"干"齒zui小值之間
How to use a Wet film Comb -

ISO 2808-7B, BS 3900-C5 method 7B, ASTM D4414-A specify that the wet film comb should be perpendicular to the substrate and the thickness of the coating should be stated as lying between the shortest wet tooth and the longest dry tooth.

Wet film combs have teeth of various lengths on their sides.

Place a comb perpendicular to, and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are "wet." Remove the comb from the film.

The wet film thickness lies between the biggest value "coated" or "wet" tooth and the smallest value "uncoated" or "dry" tooth value

Example

In the diagram, 90 is the biggest value wet tooth and 100 is the smallest value dry tooth. Therefore, the wet film thickness is between 90 and 100 mil/thou.

If the volume to solids ratio of the coating is known （if not contact the coating manufacturer） then the wet film thickness can be used to predict the dry film measurement.

To use combs on pipes, measure along the longitudinal axis （lengthways） of the pipe.

On rough surfaces, measurements will be made from the surface peaks and represent the minimum wet film thickness.
