Surface Roughness tester

Surface Roughness tester

(OP)
Hi Everyone,

I have drawings that specify the surface roughness on a a face. And to check this there are several cheap surface roughness guages. But I am wondering if there are anything like a chart where different roughnesses are pinned and you can just rub your fingers on it feel it and rub your fingers on the actual part face and feel if it is similar. Just like a paint chart that you would find in a local hardware store with different colours and finishes.

I know it is not the correct way to do inspections, but for now we are not manufacturing (prototype stage). This would be temporary check. Any help is very much appreciated.

Thanks,

I do not think you will find anything like that.
Samples where you can rub your fingers on the part , usually come in a little box, guarded like gold by the inspection dept.

Here is a link to a company that makes this stuff.

You are judged not by what you know, but by what you can do.

Amazing, this is exactly what I was looking for.

Thanks guys.

When doing the comparison use your finger nail on the surfaces. This will simulate the normal process of measuring the finish.

ICRI also has a set of comparators for concrete.
