RELATIVE HUMIDITY
There is no electronic control of humidity in these enclosures, the humidity is
maintained either by placing a small plastic tray of water in the tray support and
attaching this to a vacant shelf ladder near the bottom of the cabinet or by
partially filling the large stainless tray on cooled units. The humidity level will
usually equilibrate to a relative humidity of above 80%. (typically 60% - 70% on
Tropicool and Cooled units.
