check moisture in air?

[hbg]

Any easy way to check if there is moisture in your air line? I have a OLD air dryer and want to be sure its still doing its job. No noticeable moisture coming out when blowing air, but air is not really cold coming out the air dryer either. Having a little cut issues and just wanting to start somewhere.

Somewhere in the last few weeks on here there was a post on this subject. Someone said something about blowing the air across a cold mirror. If you see any moisture on the mirror, then you have moisture in your air. (At least that's kinda how I remember it!)
