High-Temperature Specific Heat Capacity Tester for Solid Materials

The GHC-II High-Temperature Specific Heat Capacity Tester determines the specific heat capacity of solid samples by heating a specimen to a set temperature in a vertical tube furnace and dropping it into a calorimeter, while the system records the temperature changes of both the specimen and calorimeter. The instrument integrates a vertical tube furnace, thermostat, temperature controller, high-precision thermometer, calorimeter, and a computer-based acquisition and control system.

Furnace configurations accommodate different temperature regimes: resistance wire heating up to approximately 1000°C, molybdenum wire heating to around 1700°C, and graphite tube furnace for temperatures above 1700°C. For samples that oxidize at high temperature, the system supports inert gas protection (argon) and can be equipped with a vacuum system to ensure measurement integrity.
