A high-precision automatic adiabatic calorimeter acceptance and results evaluation meeting recently took place in Dalian. This advanced instrument incorporates multi-layer insulation shielding and high-vacuum composite technology, along with a programmable constant current source for smooth heating. It is equipped with the most accurate temperature control and measurement systems available globally, enabling highly precise thermal insulation control and extremely accurate heat capacity testing.
Within the temperature range of 80K to 400K, the calorimeter exhibits a temperature drift of no more than ±1mK, with a measurement precision of ±0.2%. When compared to internationally recognized standard data, its accuracy reaches an impressive ±0.1%. Experts have stated that the technical specifications of this instrument are at the forefront of global standards, and the accuracy of key performance indicators in heat testing places it among the world's leading technologies.
This instrument plays a crucial role in providing precise thermodynamic data for studies on the heat capacity of condensed matter, phase change research, and the development of new materials. Its capabilities are expected to significantly contribute to various scientific fields, supporting advancements in material science, physics, and engineering. With such high precision and reliability, it is set to become an essential tool for researchers aiming to explore complex thermal behaviors and improve material performance in a wide range of applications.
