Fully Automatic High-Temperature Specific Heat Capacity Tester，fully automatic thermal analysis equipment for metals and composites
Fully Automatic High-Temperature Specific Heat Capacity Tester is a state-of-the-art instrument designed for measuring the specific heat capacity of solid materials at elevated temperatures. Using the mixed method and fully automated computer control, it accurately records temperature changes of the sample and calorimeter to calculate specific heat.
The tester is widely used in scientific research and teaching laboratories to investigate thermal properties of solid materials. For high-temperature, oxidation-prone samples, an atmosphere protection system can be added. The tester fully complies with GJB 330A-2000: Test Methods for Specific Heat Capacity of Solid Materials and reduces human error while improving test accuracy.
Application
The tester is suitable for:
Scientific research laboratories studying thermal properties of solids.
University and educational laboratories for teaching and demonstration purposes.
Industrial R&D to evaluate high-temperature thermal behavior of metals, ceramics, and composites.
Measurement of specific heat capacity of powders and solid samples under controlled atmospheres (e.g., argon).
Typical sample types include:
Metals, alloys, and ceramics
High-temperature refractory materials
Powders and granular solids
Materials requiring protective atmospheres during heating

Test Procedures
Prepare the solid or powder sample according to the specified dimensions.
For high-temperature, oxidation-prone samples, connect the protective atmosphere system (e.g., argon).
Hang the solid sample in the tubular heating furnace and heat to the target experimental temperature.
Drop the heated sample into the calorimeter.
The computer system automatically records temperature changes of both the sample and calorimeter.
The software calculates the specific heat capacity and generates a report.
Maintenance Information
Keep the calorimeter and heating elements clean and free from contamination.
Regularly check connections, data cables, and communication interfaces.
Calibrate the system periodically using standard reference materials.
Inspect the protective atmosphere system for leaks when testing high-temperature oxidation-prone samples.
Store the instrument in a dry, stable-temperature environment to protect electronics and heating components.
