Temperature-Humidity Con-
trol Range 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.

Temperature Pull-down Rate 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.

DOWN RATE
Temperature Range The range of temperatures that can be reproduced inside the chamber.
Temperature Uniformity The difference in temperature between the geometric center of the
chamber and any arbitrary point in the effective area.
Test Chamber A contained ambient constructed so as to obtain a desired temperature
and humidity.
Water-cooled Specification
(Water Cooled Condenser) 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.
