Fluke 5500A Multi-Product Calibrator
Overview
Fluke 5500A is the industry-benchmark multi-product calibrator that established the single-box calibration standard now carried forward by the Fluke 5502A. It sources DC and AC voltage, current, resistance, capacitance, power, phase, frequency, and thermocouple/RTD temperature signals from one chassis, and remains in active service across thousands of calibration laboratories worldwide thanks to its proven metrology performance and the deep base of existing MET/CAL and GPIB automation built around it. Many accredited labs in the region continue to operate 5500A units well within their recalibration cycle, supported by genuine parts and calibration service.
Seven Star LLC supplies the Fluke 5500A to calibration laboratories and industrial maintenance divisions across Oman and the GCC, with technical application guidance for labs maintaining legacy 5500A fleets alongside newer instruments.
Operating Principle
The Fluke 5500A uses a precision internal reference combined with closed-loop feedback amplification to source DC voltage to ±1020V at ±50 ppm accuracy, AC voltage from 1 mV to 1020V across 10 Hz to 500 kHz at ±0.03% accuracy, and DC current to ±11A at ±0.01% accuracy, continuously monitoring the load presented by the unit under test to hold these specifications across a wide range of meter input impedances. A dedicated thermocouple source-and-measure circuit with automatic cold-junction compensation extends the calibrator’s coverage to eleven thermocouple types across an unusually wide range of −250°C to +2316°C, alongside RTD sourcing across eight curve types from −200°C to +630°C.
Because voltage, current, resistance, capacitance, power, and temperature all originate from calibrated internal references within the same enclosure, a single traceability chain and a single calibration certificate cover the full function set, which is the practical reason so many labs standardized their procedures around the 5500A platform. Optional connection to the 5725A Amplifier extends current and voltage compliance beyond the base unit’s native ranges for labs calibrating higher-power test equipment.
Engineering Design of the Fluke 5500A
The Fluke 5500A is built in a rack-mountable bench enclosure with dual alphanumeric displays — one for the sourced value, one for reference and error readout — and a dedicated numeric keypad plus rotary knob for fast value entry during repetitive as-found/as-left calibration sequences. Front-panel terminals are arranged into normal voltage/current binding posts, auxiliary sense connections, a dedicated thermocouple/RTD terminal block, and a scope-output BNC connector for the optional oscilloscope calibration function, keeping the wiring changes needed between function tests to a minimum.
On the automation side, the 5500A provides IEEE-488 (GPIB) and RS-232 interfaces as standard, plus a dedicated port for the companion 5725A Amplifier when higher current or voltage compliance is required. This combination of interfaces is why so many existing GPIB-based automated calibration systems in regional labs were built directly around the 5500A, and why the instrument remains a practical, cost-effective acquisition for labs extending or backfilling an existing calibration fleet rather than migrating every station to newer hardware at once.
Key Features
The Fluke 5500A delivers broad multi-function coverage with automation interfaces proven across decades of calibration lab deployment. Its principal capabilities include:
- Sources DC voltage to ±1020V at ±50 ppm accuracy and AC voltage from 1 mV to 1020V across 10 Hz to 500 kHz.
- Delivers DC current to ±11A at ±0.01% accuracy and AC current from 29 mA to 11A across 10 Hz to 10 kHz.
- Generates resistance to 3.29 MΩ at ±0.009% accuracy and capacitance from 0.33 nF to 1.1 mF.
- Sources and measures eleven thermocouple types across an exceptionally wide −250°C to +2316°C range with automatic cold-junction compensation.
- Sources RTD resistance curves across eight configurations from −200°C to +630°C for RTD transmitter verification.
- Provides DC/AC power output from 109 mW to 11 kW with phase and frequency capability for power meter and energy analyzer calibration.
- Interfaces via IEEE-488 (GPIB) and RS-232, matching the automation architecture of long-established calibration lab test systems.
- Extends current and voltage compliance through optional connection to the 5725A Amplifier for higher-power calibration tasks.
Industrial Applications
Across Oman’s utilities, oil and gas facilities, and heavy industrial plants, calibration laboratories that standardized on the Fluke 5500A years ago continue to rely on it to maintain traceability for their existing DMM, panel meter, and temperature transmitter fleets without disrupting proven MET/CAL and GPIB-based procedures. Its wide thermocouple range makes it particularly relevant to power generation and process heating applications where temperature transmitters must be verified at extreme process temperatures, a niche not every newer calibrator covers as broadly. Refineries and petrochemical facilities in the Sohar and Salalah free zones that maintain legacy calibration equipment alongside newer instruments depend on continued access to genuine 5500A units, spares, and calibration support to keep those procedures running without a full platform migration.
Working closely with plant engineers in the region, Seven Star LLC supplies the Fluke 5500A to calibration laboratories and industrial end users throughout the Sultanate of Oman, Muscat, and the wider GCC, supporting district cooling operators, desalination plants, and cement producers that maintain accredited calibration programs built around this proven platform. Seven Star LLC’s technical support helps laboratories in Sohar, Salalah, and Muscat specify and source 5500A units, with availability and lead time confirmed at quotation.

Send the exact model with its suffix, since versions differ. A Fluke 721, for example, is defined by its two pressure ranges, and a 729 by its maximum pressure. For bench calibrators, list the options you need, such as oscilloscope calibration or power quality options, the line voltage, and the type of calibration certificate you require from the manufacturer. For Fluke multimeters and clamp meters, add the kit contents wanted, such as probes, leads or cases.Browse Fluke products by category: Portable Test & Measurement.
