When selecting a thermometer, choose one that has an upper limit which exceeds the
expected melting point of your sample.
Caution: Never heat a thermometer above its upper limit!
The thermometer must have an appropriate scale which reflects the accuracy that you
would like to achieve with your results.
Note which temperature scale the thermometer is calibrated for. Thermometers are
available to measure the temperature in Celsius, Kelvin, and Farenheit.
