High-Temperature Specific Heat Capacity Tester

The GHC-II High-Temperature Specific Heat Capacity Tester determines the specific heat capacity of solid samples based on the mixture (drop calorimetry) method. During testing, the sample is heated to the target temperature in a vertical tube furnace and then dropped into a calorimeter; the data acquisition system records the temperature changes of both the sample and the calorimeter to compute specific heat capacity.

The system integrates a vertical tube furnace, thermostatic unit, temperature controller with PID program control, high-precision thermometer, calorimeter, and a computer-based measurement system. For oxidation-sensitive materials at elevated temperatures, a vacuum system is used to protect the sample.
