Allen: I've used a similar system to the one you desribed.It is a
Plexiglass chamber 9 cu ft with an internal humidty sensor wired to
an external controller and desiccated dehumidifier w/pump for $2-3K.
The controller/dehumidifier system is also available without the box
for about $1K less.Contact Cole-Parmer 1-800-323-4340.
