Fluke 1555 10kV Insulation Resistance Tester

The Fluke 1555 10kV Insulation Resistance Tester is designed for high voltage insulation testing across motors, cables, generators, and switchgear. It provides digital readings up to 10,000 volts, giving clear and consistent results in demanding industrial settings. The device is ideal for both quick checks and scheduled maintenance routines.

With Fluke Connect wireless compatibility, this tester can capture, trend and share data remotely. Users can operate the Fluke 1555 10kV safely from up to 15 metres away, reducing time in risky areas. It lets you store and label up to 99 readings, keeping your records tidy and easy to access.

Streamlined Data Handling

You can use the mobile app to share readings instantly with colleagues through ShareLive video calls. You can add notes, images and values to job orders as you go. The Fluke 1555 10kV displays visual trends on screen, helping you spot patterns and find faults before they cause failures.

Reliable Performance in Harsh Conditions

Built to meet CAT IV 600 V and CAT III 1000 V safety standards, this tester is ready for industrial use. With a strong case, clear LCD, and rechargeable power supply, it offers over 750 tests per charge. The 3-year warranty gives extra peace of mind.

Key Features
  • Insulation testing selectable from 250 V to 10 kV
  • Compatible with Fluke Connect for remote operation
  • Wireless app helps share, store and review test results
  • Measures insulation resistance up to 2 TΩ
  • Built-in memory saves up to 99 labelled readings
  • Calculates DAR and PI automatically
  • Ramp function included for insulation breakdown testing
  • Reads leakage current and capacitance directly
  • Includes line voltage warning with voltage display up to 600 V
  • Up to 99 minutes timer for custom test durations
  • Long battery life supports over 750 tests per charge
