Great post.

Yes, using a shower is a great way to move into a very humid environment.

For dry environments, you could also use your oven at low temperatures. You can put your sensors under the heating elements, which should give you the driest location in the oven.

As @John Wiltrout stated, you can reheat the little moisture packs to make them absorbent again.

In my early days at the laser lab I had to do this weekly to keep our more sensitive crystals dry.

Hi David,

If those little bags of silica Gel are left out they can become saturated and may no longer work. Putting them in a very dry environment for a while or heating them can rejuvenate them. Heating can be problematic as the bags can burn. Several weeks in a freezer where the dew point is very low may do the trick.
