5520A Fluke Multifunction Calibrator


The 5520A is a Multifunction Calibrator from Fluke. Engineers may need a sound level calibrator, radio frequency calibrator, power-meter calibrator, voltage-current calibrator, or another type for electronic test equipment calibration. Electronic calibrations are necessary for maintaining your equipment for general monitoring and testing purposes. Calibrators enable you to solve problems with your equipment on your own, on site.

The Fluke 5520A Multi-Product Calibrator sources direct voltage and current, alternating voltage and current with multiple waveforms and harmonics, two simultaneous voltage outputs or voltage and current to simulate DC and AC power with phase control, resistance, capacitance, thermocouples and RTDs.

The 5520A can also measure thermocouple temperature, humidity (with probe) and pressure using one of 28 Fluke 700 Series pressure modules.

The Fluke 5520A builds on the 5500A's capabilities, extending its workload coverage even further. Its improved accuracy, expanded ranges, and capability to calibrate 5-1/2 and 6-1/2 digit multimeters can cover virtually all your high-performance workload.
