Insulation tester 2.5kV

The Fluke 1535 and 1537 insulation testers are designed to simplify on-site troubleshooting, both in industrial facilities and on solar power plants. With user-selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 Ω, these testers allow you to accomplish more tasks with a single tool. Featuring an intuitive user interface, a short-circuit current of up to 5 mA, and CAT IV 600 V safety rating, these portable high-voltage insulation testers provide fast and reliable resistance measurements anywhere. The 1537 also allows you to save measurements using the included software for later review or transfer to a PC.

Selectable test voltages

For your insulation tests, set voltages of 250 V, 500 V, 1,000 V and 2,500 V to cover both industrial and solar applications.

Extended insulation resistance measurement

Perform insulation resistance measurements up to 500 GO for a thorough analysis.

Intelligent calculations

Automatically calculate the polarization index (PI) and dielectric absorption coefficient (DAR) to minimize the influence of environmental factors.

Many measurements with one battery set: Increase productivity and perform up to 1,300 measurements at 2,500 V or 6,500 measurements at 250 V.

Improved security features

Benefit from safety according to CAT IV 600 V and alarm for hazardous voltages for increased safety during operation.
