FAQ

1. What type of samples can this tester test?

This tester can measure both solid and powder materials, including metals, ceramics, alloys, and granular samples. Solid samples should have a diameter of 11–14 mm and height of 20–40 mm, while powders require approximately 6 cm³. For oxidation-prone materials, the instrument can be equipped with an argon atmosphere system to prevent sample degradation at high temperatures.

2. How is the specific heat capacity measured?

The tester uses a mixed method, where the sample is first heated in a tubular furnace to the experimental temperature and then dropped into a calorimeter. The system records temperature changes of both the sample and calorimeter. Using these measurements, the software calculates the specific heat capacity automatically. The fully automated process reduces human error and ensures high precision.

3. What is the temperature range for testing?

For atmospheric measurements, the instrument can operate between 100–800°C using resistance wire heating. For high-temperature applications with an argon protective atmosphere, it can operate between 200–1350°C with silicon carbide tube heating. Temperature control and monitoring are handled by an intelligent PID system to ensure stability and accuracy.

4. How accurate is the tester?

For solid materials, the measurement accuracy is ≤1% ± 0.002. and for powders, ≤2% ± 0.002. The instrument uses computer-controlled data acquisition and intelligent PID temperature regulation, reducing human error and providing consistent, repeatable results for research and industrial applications.
