The Fluke 1662 Multifunction Tester & T90 Voltage Tester Kit covers everything from installation testing to quick and safe voltage checks.
The Fluke 1662 provides all the core testing procedures needed for domestic, commercial, and light industrial installations in line with IEC 60364 standards. It includes RCD tripping current ramp tests, insulation resistance up to 1000 MΩ, loop and line resistance testing, and True RMS AC/DC voltage measurement up to 500V.
The Fluke T90 covers a voltage range of 12V to 690V, has a bright LED indication, GS38-compliant tip caps, and WearGuard test lead indicators. Together, these two instruments create a kit that balances in-depth installation testing with rapid everyday safety checks.
