Product Features:
1. The system can automatically complete the entire process of measuring, controlling, recording, and data processing of the resistance-temperature characteristics of high-Tc superconducting materials.
2. The measurement system circuit uses an ARM core microcontroller with a WATCHDOG circuit, offering high reliability and strong anti-interference performance.
3. Integrated design of measurement instruments and matching test probes.
4. Utilizes low-drift preamplifiers and high-resolution, high-speed acquisition chips.
5. Can also be used for resistance-temperature characteristic measurements of other samples.
6. Automatic alternating forward and reverse measurements with averaging to minimize data errors.
7. Composed of a cryostat with installed samples, temperature measurement, data acquisition, communication, and computer software for processing systems.
