How to Measure Wet Film Thickness using Elcometer Wet Film Wheels

The Elcometer 3230 Wet Film Wheel is a high precision, accurate and easy to use instrument which measures the wet film thickness of coatings.
A wet film wheel has two circular outer wheels which rest on the substrate, and a smaller central wheel which is eccentric relative to the outer wheels.
By rolling the gauge through a wet coating, the central wheel eventually touches the film. This point on the scale indicates the thickness.
This Elcometer 3230 Coil Coating Wet Film Wheel is designed for use in the coil coating process. The outer wheels are knurled to allow measurements to be taken on slippery coatings or on fast moving substrates.
Elcometer offer a wide range of wet film wheels to measure wet films of various thicknesses. For more information on Elcometer wet film wheels, please contact Elcometer at [e-mail] or visit our website at www.elcometer.com

I have no idea what occupation these are for or even what was being said but this was a well made video with good pacing! If I ever need to use an Elcometer at least Ill know how to use it!

Hey i am using the wet film wheels and find this video really nice, hence i can not acces the standard. Thank you for your work.
Any chance you know what the hole at min 3:33 is used for? I always wondered.

[@ElcometerOfficialChannel]

Thank you for your comment.
It's great to hear you find the video useful!
The hole is there as a result of the machining process, so it doesn't have any use in terms of how you use the wheel, just how it is made.

hi,when we use this wheel,when it moves 360 degree,there should be two readings (on each half - ie 180 degree rotation),so how we calculate the final reading??by taking average or taking the highest value??

[@ElcometerOfficialChannel]

Thank you for your comment.
In accordance with the latest versions of ASTM D 1212 and ISO 2808, you take the average of the two readings.
