Fluke 1507 Insulation Resistance Tester

The Fluke 1507 is a compact, rugged insulation resistance tester designed for electrical contractors, industrial maintenance, and commercial electricians. With multiple test voltages (50–1000 V), PI/DAR calculations, and built-in safety functions, it ensures reliable diagnostics in commissioning, troubleshooting, and preventive maintenance.

Key Features & Benefits

• Wide Measurement Range: Insulation resistance 0.01 MΩ to 10 GΩ, with selectable test voltages from 50 V to 1000 V.
• Safety Built-in: Live circuit detection inhibits tests above 30 V; auto-discharge protects users from residual voltage.
• Multi-Function Tester: Measures AC/DC voltage to 600 V, resistance 0.01 Ω–20 kΩ, and continuity with 200 mA test current.
• Efficiency: Remote probe simplifies repetitive or hard-to-reach testing; large backlit display improves visibility.
• Portable & Durable: Lightweight (550 g), IP40 rated, and delivers over 1000 insulation tests per set of AA batteries.

Typical Applications

• Routine insulation verification for electrical contractors
• Motor, cable, and switchgear testing in industrial maintenance
• Commissioning compliance testing in new installations
• Solar and renewable energy insulation safety checks
• Preventive maintenance in commercial facilities
