The range in which temperature and humidity can be reproduced inside
the chamber. It is normally expressed as a graph with temperature as the
x-axis and humidity as the y-axis.

The time required for the temperature to change from a defined tempera-
ture t1 to a defined lower temperature t2. This is simply the time required
for the drop in temperature and does not include the time it takes for the
temperature to stabilize.

The range of temperatures that can be reproduced inside the chamber.
The difference in temperature between the geometric center of the
chamber and any arbitrary point in the effective area.
A contained ambient constructed so as to obtain a desired temperature
and humidity.
The condenser in the refrigeration circuit is cooled by water. Usually, a
cooling tower or similar unit is used to supply water and cool heat gener-
ated by the condenser. The water-cooled specification is an option with
Platinous Sterling Series Chambers.
