Fluke 1503 Insulation Resistance Meter

The Fluke 1503 is a great choice for basic residential and commercial electrical insulation testing. This rugged, compact tool fits in the palm of your hand. The 1503 is the same form factor as the Fluke 1507 but with a few less features. You can count on it to handle the most common tests at a most affordable price. Additional features, like the remote probe, reduce the time needed to perform repetitive testing.

• Measures AC/DC voltage from 0.1 V to 600 V
• Includes auto-discharge of capacitive voltage for added user protection
• Provides lo-ohms earth-bond continuity (200 mA)
• Simplifies repetitive or hard-to-reach testing with the remote test probe
• Saves battery power with auto power off
• Presents results on a large, backlit display
• Features CAT IV 600 V overvoltage category rating
• Comes with remote probe, test leads, test probes, alligator clips, and one-year warranty
• Accepts optional Fluke TPAK magnetic hanging system to free your hands for other work
• Runs on four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests
  
• Included accessories: TL224 Test Leads, TP74 Test Probes, clips PN 1958654 (red) and PN 1958646 (black), holster and remote probe
