Fluke 1535/1537 Insulation Resistance Tester (2500V)

Fluke 1535/1537 Insulation Resistance Tester (2500V)

Description

The Fluke 1535 and 1537 are high-voltage insulation resistance testers engineered for demanding industrial and solar applications. With user-selectable test voltages from 250V to 2500V and resistance measurements up to 500 GΩ, these testers let you cover more workload with a single compact tool — whether you are working on a factory floor or a solar installation in Karachi or across Pakistan.

Both models feature an intuitive user interface, a short circuit current of up to 5mA, and a CAT IV 600V rating for rapid, stable insulation resistance measurements in any environment. The Ramp Test mode linearly increases voltage at 100V/s to identify hard-to-find fault conditions, while the Dielectric Discharge Rate (DD) calculation helps uncover elusive insulation issues. The 1537 adds data storage with PC transfer capability via included software and extends measurement to AC/DC voltage and resistance.

Why Choose the Fluke 1535/1537?

Fine-tunable test voltage in 100V increments from 250V to 2500V gives unmatched flexibility for both standard and specialized testing requirements. Visual and audio continuity indication lets you focus on the test without constantly looking at the display. Built for rugged field use with IP-rated protection and 8 AA batteries for extended use without recharging.
