英國易高Elcometer 3230濕膜輪正如Elcometer 120一樣由三個圓輪組成。中心的圓輪直徑較小，其圓心與外側的兩個圓輪的圓心不同。沿濕膜滾動濕膜輪，中心輪濕潤部分末端的讀數(shù)即為濕膜厚度。
如果知道涂層的干、濕比率，便可通過濕膜厚度計算干膜厚度。
不同的測量量程從0~25μm（0~1mils）至0~3000μm（0~40mils）。

連續(xù)刻度，測量精確度為±5%。
適用于平面和曲面測量。
不銹鋼材質，耐磨損，用溶劑清洗后可重復使用。

How to use a Wet Film Wheel - Elcometer 3230 Wet Film Wheel

ISO 2808-7B, BS 3900-C5 method 7B, ASTM D4414-A specify that the wet film wheel should be perpendicular to the substrate and the thickness of the coating should be stated as that indicated on the central wheel - ensuring that the wheel has been rolled from maximum thickness to minimum thickness - thus avoiding surface tension.

Example

Hold the wheel by its central spindle. Begin at maximum thickness to reduce risk of inaccuracy caused by surface tension.

Roll the wheel through the wet film with the side 1 in the diagram touching the substrate. Roll for at least one whole turn and slowly enough for wetting to occur. Roll the wheel backwards by at least on complete turn. The wet film thickness is read from the scale, at the end of the wetted segment of the middle circle, 2 in the diagram

To use wheel on pipes, measure across 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.
