lower than the solidification point of the sample (10±1)℃;
b) Inject the sample into the dry and clean inner tube. Make the liquid level 50 mm;
c) Fix the platinum resistor in the center of the inner tube with a cork or rubber plug.

b) Pour the sample into a dry, clean beaker. Immerse the electrode 30 mm below the
sample and 10 mm above the bottom of the beaker. The electrode cannot touch
the bottom and side walls of the beaker.
6.3.3 Results
