Fluke 1507 | 1000V Digital Insulation Tester with PI/DAR & Pass/Fail

Different electrical equipment can require different insulation-test voltages, particularly when low-voltage controls and larger motors must be checked with the same instrument. The Fluke 1507 Digital Insulation Resistance Tester provides five selectable test voltages from 50 V to 1000 V and insulation measurement up to 10 GΩ.

Automatic Polarization Index and Dielectric Absorption Ratio calculations help technicians evaluate insulation condition over time, while the Compare function provides Pass/Fail indication for repetitive testing against selected limits. The tester also measures AC/DC voltage to 600 V and includes 200 mA continuity testing for earth-bond and winding checks. Live-circuit detection and automatic capacitive discharge support safer field operation. Compared with the 1503, the 1507 is the more versatile preventive-maintenance instrument.

Advanced Handheld Insulation Tester Selection Guide

Choose the 1507 when you need 50, 100 or 250 V tests in addition to 500/1000 V, or when PI/DAR and repetitive Pass/Fail testing improve your maintenance program.

Market Relevance

The Fluke 1507 is well suited to Pakistan's industrial plants, motor-rewinding workshops, utilities, HVAC contractors and electrical maintenance departments. Kamadi Pakistan offers the Fluke 1507 for versatile insulation-condition testing and commissioning.
