High-precision automatic adiabatic calorimeter project passed the acceptance

A high-precision automatic adiabatic calorimeter acceptance and results evaluation meeting recently took place in Dalian. This advanced instrument employs multi-layer insulation shielding combined with 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 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 device are at the forefront of global standards, and its performance in heat capacity testing has achieved an international leading level. This instrument provides highly accurate thermodynamic data for studies on the heat capacity of condensed matter, phase transitions, and the development of new materials. Its capabilities are expected to play a crucial role in various scientific research fields, including material science, physics, and engineering. With its cutting-edge design and exceptional accuracy, this calorimeter represents a significant advancement in thermal analysis technology, offering researchers a powerful tool to explore complex thermal behaviors with unprecedented precision.
