How to measure part dryness?

(OP)
Hi Guy,

I got a question. How do i measure part dryness?

I have an application that require to water wash and blow dry a shock adsorber shaft. Is there a way to measure how dry the shaft is after blow drying?

Appreciate all help here.

RE: How to measure part dryness?

Dryness is relative, it depends on atmospheric conditions in which you measure. RH, Dry Bulb temperatue, wet bulb temperatures, pressure (barometric) and dew point also plays a role.

There are various methods to verify dryness of an enclosed space, in your case it happens to be your shaft (external surface), so if you are in ambient condition (20 Deg C and 1 atm) then simple wrap with bloting paper should let you know whether the item is dry enough.

On the otherhand if you have a specificaiton (dryness level defined) then appropriate method can be improvised from the existing ASTM methods for soil, concrete and aggregate, but again these methods may involve weighing and heating etc.

If the manual simply said the shaft has to be dry, without defining the dryness limit, then all you need is to blow hot air and if you do not feel any residue or mositure on surface, that is a test enough (Average human touch / feel) is a good test of dryness.
