Kewtech KT63PLUS 18th Edition Multifunction Tester

Kewtech KT63PLUS banner

The Kewtech KT63 PLUS 18th edition multi-function tester builds on the already popular Kewtech KT63DL. The KT63 PLUS is compact and very easy to use, it is also IP54 rated for protection against dust, moisture and the British weather! Added to this, the unit comes with a soft carry case for safe storage and transport when not in use.

The KT63 Plus is an exceptionally capable tester despite its small form factor. The improved, larger screen (compared to the standard KT63) is much more practical. For example, all six auto RCD test results are displayed on one screen at the same time, removing the need to scroll through. Furthermore, phase rotation is now indicated visually by rotating disks.

As with the Kewetch KT64DL, KT65DL and KT66DL, testing with the KT63 PLUS can be started in one of three simple ways…

  • Single test button press
  • Press, twist and lock test button for continuous hands-free testing
  • Via the button on the included remote test probe
