The Fluke 1503 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: 0.1 MW to 2000 MW (1503 only)
• Insulation test voltages: 500 V, 1000 V
• 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
