■Performance Features
1Runs on Windows environment, with easy and quick mouse click operations.
2Utilizing a six-and-a-half-digit high-precision thermocouple resistance tester, the system is simple in structure, reliable, and cost-effective.
3The temperature points for calibration can be set arbitrarily. During the calibration of resistance thermometers, it achieves automatic conversion between two-wire, three-wire, and four-wire systems, making it convenient and practical.
4Automatically tune the PID parameters for temperature control, making the temperature control process faster, more precise, and more stable.
5Simultaneously controlling five calibration furnaces, its unique structural design is at the forefront domestically. If a fault occurs in one path during the calibration process, the other paths remain unaffected.
6Offering two modes of automatic tracking compensation for the cold end at zero and room temperature for user selection.
7With automatic detection of wiring errors and over-temperature protection features.
8With features for storing, previewing, and managing calibration records, users can review or print results reports from any previous calibration.
