Fluke 5720A High Performance Multifunction Calibrator with ±3.5 ppm DC Voltage Accuracy and 1100V AC Voltage Range

The Fluke 5720A is the industry-standard high-performance multifunction calibrator trusted by national metrology institutes and calibration laboratories worldwide. It delivers DC voltage to ±1100V, AC voltage to 1100V from 10 Hz to 1 MHz, current to 11A (110A with 5725A amplifier), and resistance to 100 MΩ with exceptional accuracy and long-term stability.

• Industry-Leading DC Voltage Accuracy: ±3.5 ppm DC voltage accuracy with outstanding 24-hour and 90-day stability specifications
• Wideband AC Voltage Generation: 220 mV to 1100V AC from 10 Hz to 1 MHz with ±45 ppm amplitude accuracy
• Precision Current Output: DC and AC current to 11A standard, expandable to 110A with Fluke 5725A amplifier
• Comprehensive Resistance Function: Programmable resistance values from 0Ω to 100 MΩ with high accuracy
• Artifact Calibration System: Internal 10V DC and 10kΩ precision references enable self-calibration
• DC/AC Voltage Ratio Traceability: Unique AC/DC transfer measurement capability ensures traceable AC voltage calibration

The 5720A can be paired with the optional Fluke 5725A Power Amplifier to extend current output to 110A and voltage drive capability up to 1100V with higher burden tolerance. The two units integrate seamlessly with shared control via the 5720A front panel or remote interface.
