The KT66DL multifunction tester, combined with our ACCES earth spike kit, is the most cost effective way to obtain an instrument that will test TN, TT and independent earthing systems.

The spike kit fits into the KT66DL carry case so everything can be kept together in one place.

The KT66DL comes with CD-ROM software but if you would prefer to download the KEW REPORT software you can do so here…Download Software.
