The Fluke 5520A Multi-Product Calibrator combines precision sources for voltage, current, and resistance in a single chassis, delivering exceptional performance for calibration applications. With typical 11 ppm DC accuracy and wide-band AC outputs to 500 kHz, this calibrator provides a 4:1 test-uncertainty ratio when calibrating various measurement instruments.

• Voltage Range: ±1020 V DC and AC
• Current Range: ±20 A DC and AC
• Resistance Range: Up to 100 MΩ
• DC Accuracy: 11 ppm typical
• AC Bandwidth: Up to 500 kHz
• Supported Instruments: 6½-digit bench meters, handheld DMMs, clamp meters (with external current booster), and power analyzers

• Programmable harmonics and phase control for comprehensive testing
• Built-in MET/CAL® procedures to significantly reduce setup time
• GPIB/RS-232 connectivity for seamless integration into automated systems
• External current booster capability for clamp meter calibration

Every unit ships with an ISO/IEC 17025 calibration certificate (TESTRO Certified) tied to its serial number.

High-resolution teardown photos plus live video testing (gain-linearity, noise-floor, spurious response); recordings are stored for the product's lifetime.

One-year warranty and weekday remote assistance from our in-house engineering team for both software and hardware issues.

Aviation-grade flight case with triple-layer anti-vibration foam and shock/tilt indicators; priority DHL delivery in 3-5 days to major destinations.

Accepts T/T, wire transfer, and credit card payments.
