Fluke 77-4 Industrial Multimeter - Fluke-77-4

The Fluke 77-4 Industrial Multimeter is a trusted workhorse in the Fluke product line, a 1000V CAT III industrial meter with established reliability in industrial maintenance, manufacturing, and process facilities worldwide. The 77-series has been specified in maintenance manuals, tool lists, and calibration programs for decades, making the 77-4 a direct replacement and continuation of the most widely deployed Fluke model family in industrial environments. For facilities with existing 77-series meters in their calibration programs, the 77-4 provides seamless fleet continuity.

Key Features

• 1000V Industrial Rating: Full 1000V AC/DC measurement range for industrial distribution, motor control center, and high-voltage equipment diagnostics.
• CAT III 1000V Safety: Rated for secondary distribution and industrial panel measurements at industrial voltages up to 1000V.
• 6,000-Count Display: Professional resolution with backlight for panel and equipment room work in low-light conditions.
• Established Fleet Continuity: The 77-series is among the most widely specified Fluke models globally, calibration programs, GSE lists, and maintenance manuals that reference "Fluke 77" meters can be updated to the 77-4 without requalification of the instrument type.
• Full Measurement Suite: AC/DC voltage, current, resistance, capacitance, frequency, continuity, and diode test.
• Min/Max Recording: Captures measurement extremes during load changes and motor start events.

Industrial Applications

• Direct replacement for 77-series meters in existing calibration programs
• Industrial panel and MCC voltage measurement at 1000V
• Motor circuit verification and troubleshooting
• General industrial electrical maintenance where 77-series is the established standard

Fluke 77-4 Calibration

PJi operates an ISO/IEC 17025 Accredited Calibration Lab and provides NIST-traceable calibration for the Fluke 77-4 at the time of purchase, add calibration to your order at checkout. Our calibration documentation satisfies FAA Part 145 tool control requirements, ISO 9001 quality system records, and AS9100 calibration traceability requirements. For repair stations and quality-certified facilities that require documented traceability, PJi is the one-stop source: the instrument and the calibration certificate in a single transaction. Calibration-only companies cannot sell you the instrument. Major retailers cannot calibrate it. PJi does both.

Why Buy from Pilot John International

Pilot John International is an authorized Fluke distributor with specialized expertise serving aviation maintenance, FAA Part 145 repair stations, and industrial MRO facilities. Unlike Amazon, Grainger, or Test Equipment Depot, which sell Fluke instruments but offer zero calibration services, PJi's in-house ISO/IEC 17025 Accredited Calibration Lab calibrates your instrument at purchase. We stock the full Fluke catalog, ship same-business-day on in-stock items, and our technical staff understands the demands of aviation and industrial electrical maintenance.
