TI1200 Precision DC Resistance Calibrator
TI1200 is a high-precision DC resistance source with an exceptionally wide output range, designed for accurate on-site calibration of ohmmeters and other resistance measurement devices. It is ideal for industrial production lines, laboratories, and quality control environments where precise resistance calibration is critical. The instrument supports calibration of DC resistance meters, digital multimeters, DC bridges, microohmmeters, and high-resistance instruments up to 1000 MΩ, providing reliable performance across a vast range of applications.
The TI1200 offers both four-terminal and two-terminal measurement modes, ensuring high accuracy even for low-resistance measurements where lead resistance could introduce errors. Its output features ultra-fine adjustment capability, low ripple, and selectable manual or automatic range switching. Protective mechanisms, including reverse connection protection, overload protection, and overheat protection, make it safe for repeated use in demanding industrial and laboratory environments.
With a high-resolution 7-digit display and adjustable output, the TI1200 ensures precise reading and calibration of resistance values. Its robust communication interfaces (USB, LAN, RS232) allow easy integration into automated calibration setups, while its compact and lightweight design makes it suitable for on-site calibration tasks. Whether for low-ohm or high-megaohm calibration, the TI1200 provides accuracy, stability, and versatility to meet modern measurement standards.
