Fast, accurate and reliable insulation tests in a lightweight, portable package

The Fluke 1535 and 1537 2500 V insulation resistance testers are designed to simplify first-line troubleshooting, whether you are on the factory floor or working on site at a solar installation. With these testers, where the user can select test voltages from 250 V to 2,500 V and with resistance measurements up to 500 GOhm, you can do more work with a single instrument. Featuring an intuitive user interface, a short-circuit current of up to 5 mA and a CAT IV specification of 600 V, these portable high-voltage insulation testers can make fast and stable resistance measurements wherever you take them. The 1537 Insulation Resistance Tester also allows you to save measurements for later review or transfer via PC using the supplied software.

  • Selectable voltage tests: Customise your tests with user-selectable voltages of 250 V, 500 V, 1,000 V and 2,500 V for both industrial and solar energy applications.
  • Extended insulation resistance measurement: Achieve insulation resistance measurement up to 500 GOhm for in-depth analysis.
  • Intelligent calculations: Automatically calculates polarisation index (PI) and dielectric absorption ratio (DAR, Dielectric Absorption Ratio), minimising the influence of environmental factors.
  • High measurement capacity: perform up to 1,300 measurements at 2,500 V or 6,500 measurements at 250 V with a single set of batteries, increasing productivity.
  • Enhanced safety features: Benefit from a CAT IV specification of 600V and a built-in voltage alarm function for increased safety during operations.
