I have thought of using weight but this is stainless steel shaft that weigh around 1 to 2 pounds. The weight of water on the shaft will be insignificant to measure.
My customer suggested a contamination target to be <0.7ppm. I have no idea how i can measure this.
Is there any method to measure the dryness. In the harddisk industry, they uses Karl Fischer. I am not sure if this is good for this application. it seem like overkill
to me. Is there any process in the automobile industry that really measure part dryness before assembly?
My customer is not in favour of visual dryness.

What's the purpose anyway? Is it to prep for coating?

Thanks for the advise, i will check with the customer on this. This process could be too length and they might not accept it.
This is the shaft of the car absorber. They dun wan any water to go inside the chamber which cause corrision.
