The Fluke 1507 and 1503 Insulation Testers are compact, rugged, reliable, and easy to use. With their multiple test voltages, they are ideal for many troubleshooting, commissioning, and preventative maintenance applications.

Additional features, like the remote probe on these tools save both time and money when performing tests.

  • Insulation test range:  0.01 MΩ to 10 GΩ (1507) or 0.1 MΩ to 2 GΩ (1503)
  • Insulation test voltages: both: 500 V, 1000 V  1507 only: 50 V, 100 V, 250 V
  • Automatic calculation of Polarization Index and Dielectric Absorption Ratio (1507)
  • Compare (Pass/Fail) function (1507)
  • Repetitive or hard-to-reach testing is easy with the remote test probe
  • Live circuit detection prevents insulation test if voltage > 30 V is detected for added user protection
  • Auto-discharge of capacitive voltage for added user protection
  • AC/DC voltage: 0.1 V to 600 V
  • 200 mA Continuity
  • Resistance: 0.01 Ω to 20.00 kΩ
  • auto power off
  • large, backlit display
  • CAT IV 600 V overvoltage category rating
  • Remote probe, test leads, probes and alligator clips included with each tester
  • Accepts optional Fluke TPAK magnetic hanging system
  • Four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests
  • One year warranty
