Humidity Gradient
The difference in humidity between the highest and lowest
humidity points within the working space after stabilization.
Lowest Attainable Temperature
The lowest temperature that can be reproduced inside the
chamber.
Rated Load Current
The maximum amount of electric current the chamber will
draw through the power cable when the chamber is running
within the temperature and temperature-humidity control
range.
Overheat Protector
A device for preventing temperature inside the chamber from
rising abnormally high because of chamber trouble or heat
generated by specimens.
Specimens Power Supply Control
Terminal
A terminal to charge specimens, which is interlocked with the
chamber power circuit so that power to specimens is shut
OFF in the event of chamber trouble.
Temperature Fluctuation
The variation between the mean maximum temperature and
mean minimum temperature around the geometric center of
the chamber. Not the same as the difference from the true
temperature.

Temperature-Humidity Control
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.
