Hygrometer

[Don]

Hi Richard,

Please notice the word *local* as in location. Where I live the only
practical way to achieve "perfect" control on an "art gallery" level is to
have three layers. A large building with an outer shell where there is
little attempt to control humidity except to keep it low enough to prevent
damage to outside walls, then a "buffer zone" where humidity is kept
somewhat higher, and finally a super controlled area where the delicate
object of arts are kept. 

If we accept that building costs are say $20.00 per square foot (a
ridiculously low price) and that a full blown DC system costs $2000.00 (a
ridiculously high price) one can certainly see the "economics" of this
approach compared to the box within a box within a box.

In any event this "three layer approach" is the exact situation that our
local gallery has. They have a small grand piano. It is rarely able to
survive a twenty-four hour period where it can stand in tune due to
humidity changes.

One of our local music schools has a similar structure--but with a very
small recital hall. The room had exquisite control of humidity and
temperature. One summer the humidity controller failed. There was no money
in the budget (a paltry sum of $150.00 was needed) Of course that winter,
the soundboard on the instrument cracked and all the hammer shanks warped. 

So I repeat my claim. Give me a "perfect" room in the "real world", and
I'll add a "perfect" DC system in my local, and improve on the stability of
the instrument.
