Fluke 1503 Insulation Resistance Tester - Fluke-1503

The Fluke 1503 Insulation Resistance Tester provides basic 500V and 1000V insulation resistance measurement at the entry level of the Fluke insulation tester line, without the PI/DAR testing, automatic discharge, and programmable thresholds of the 1507. For technicians whose maintenance program requires only a go/no-go insulation resistance reading at a specified minimum value, rather than analytical PI or DAR ratio calculation, the 1503 delivers accurate insulation resistance measurement at the two most common test voltages in a straightforward, easy-to-operate instrument.

Key Features

• 500V and 1000V Test Voltages: The two most common insulation test voltages for wiring (500V) and motor winding testing (1000V) without the multi-voltage complexity of higher-tier models.
• Insulation Resistance to 2,000MΩ: Full measurement range from failing insulation through newly commissioned equipment values.
• Simple Operation: Select test voltage, connect test leads, apply to test object, read result. The 1503's straightforward operation reduces training requirements and operator error on routine insulation testing tasks.
• Continuity Testing: Basic circuit continuity verification alongside insulation testing.

Applications

• Routine insulation resistance checks at 500V or 1000V per maintenance specification
• Basic go/no-go insulation verification without PI/DAR analysis
• Entry-level maintenance programs establishing initial insulation testing capability

Fluke 1503 Calibration

PJi operates an ISO/IEC 17025 Accredited Calibration Lab and provides NIST-traceable calibration for the Fluke 1503 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 traceability requirements. PJi is the one-stop source: the instrument and the calibration certificate in a single transaction. Calibration-only companies (Custom-Cal, Fox Valley Metrology, ATS) cannot sell you the instrument. Amazon and Grainger 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.
