  • High-temperature calorimeter

    This product uses the drop isotherm method to test the specific heat and melting enthalpy of samples at different temperatures. Compared with traditional DSC, this equipment uses a sealed crucible and does not directly contact the calorimeter, which can effectively avoid testing difficulties caused by sample corrosion, overflow, volatilization, etc. In the measurement of high-temperature volatile samples such as molten salt, the testing accuracy is better and the reproduction is better.

    Scope of application

    It can directly measure the enthalpy value, specific heat, and temperature variation of condensed matter at high temperatures; The experimental measurement results can also calculate thermodynamic parameters such as entropy and Gibbs free energy of condensed matter in the high-temperature region; For high-temperature thermal storage materials - molten salts, their sensible heat, phase change latent heat, phase change temperature, thermal storage density, and melting temperature can be analyzed.
