Fluke 5500A With 5500A/LEADS — ±1020 V / 11 A Multifunction Calibrator, 50 ppm DC Accuracy Multi Function Calibrator

The Fluke 5500A is a laboratory-grade multi-product calibrator that sources precision DC/AC volts to 1020 V, current to 11 A, resistance to 3.29999 MΩ, and capacitance to 1.1 mF, with wide AC coverage to 500 kHz. Best 1-year DCV performance is 50 ppm, enabling low-uncertainty calibration of DMMs, clamp meters (with 5500A/COIL), recorders, and process instruments. Standard GPIB and RS-232 support automated procedures; the unit integrates with the 5725A amplifier and 52120A for high-current workloads. This unit includes the 5500A/LEADS accessory kit—shielded leads, 30 A leads, thermocouple adapters/extensions, and a soft case—streamlining connections and reducing thermal/connection errors. Calibration certificates are available on request.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
