Introduction
The Hart Scientific 9116A Furnace has a temperature range of 550°C to
1100°C and is designed for use in achieving aluminum, silver, or copper freez-
ing point measurements.
The furnace utilizes a sodium heat pipe to maintain a uniform temperature over
the length of the metal freeze point cell. The temperature controller is program-
mable, a feature that may be conveniently used to simplify the melting, freeze
initiation, and plateau control. The temperature control and uniformity of the
furnace allows the user to achieve plateaus ranging many hours in length.
NOTE:
Many of the illustrations and examples used in this manual as-
sume the use of the copper point cell. Any of the three cells indicated may
be used with the appropriate set-points.
