temperature, metal vessels and sand baths
may be heated safely without the danger of
the ceramic top breaking.
When heating metal vessels and sand baths
however, we recommend that you DO NOT
use the probe to control the temperature.
Because of the heating and cooling properties
of metal and sand, the sample temperatures
fluctuate, which will result in unstable top
plate temperatures. We achieved better
results controlling the top plate temperature,
which allowed us to maintain a constant level
of heat to the sand bath or metal vessel. The
top plate setpoint should be set approximately
100° above the temperature required for your
sample, and the sample temperature may be
monitored with a standard laboratory
thermometer.
