The Fluke 1535 and 1537 Insulation Testers allow 2.5kV testing across a wide range of equipment and applications. Fast, accurate, reliable insulation testing in a portable lightweight package.

These digital CAT IV 600V insulation testers offer:

• Easier accuracy: Built-in PI (Polarisation Index), DAR (Dielectric Absorption Ratio), and DD (Dielectric Discharge) test functions exclude environmental factors. Short circuit current up to 5 mA for faster readings that stabilize quickly, increase accuracy, and save time.
• Efficiency: Small, lightweight, and easier to use in tight spaces or at heights. Quick set up reduces testing time. Make more measurements on a single charge.
• Wider workload coverage: Adjustable testing voltages up to 2500 V and up to 500 GΩ insulation resistance. Suitable for industrial and solar applications.

Fluke insulation testers are designed to be safe in your environment, simple to use, and accurate for your troubleshooting, commissioning, and preventive maintenance applications.
