* Required Fields

The Fluke 1507 Insulation Testers is 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.

Features and benefits:

  • Insulation test range: 1507: 0.01 MW to 10 GW
  • Insulation test voltages: 1507: 50 V, 100 V, 250 V, 500 V, 1000 V (1507 only)
  • Save both time and money with Automatic calculation of Polarization Index and Dielectric Absorption Ratio
  • Make repetitive tests simple and easy with the 1507’s Compare (Pass/Fail) function (1507 only)
  • 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 W to 20.00 KW
  • Save battery power with auto power off
  • Read measurements easily with large, backlit display
  • CAT IV 600 V overvoltage category rating for added user protection
  • Remote probe, test leads, probes and alligator clips included with each tester
  • Accepts optional Fluke TPAK magnetic hanging system to free your hands for other work
  • Four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests
  • One-year warranty

Included accessories

  • TL224 Test Leads,
  • TP74 Test Probes
  • Clips PN 1958654 (red) and PN 1958646 (black)
  • Holster and remote probe
