Kewtech KT66ET Bundle – KT66DL Multifunction Tester with Earth Spike Kit
Bring earth resistance and electrical installation testing together in one practical bundle.
The Kewtech KT66ET Bundle combines the KT66DL 12-in-1 Multifunction Tester with the ACCES earth spike kit for testing TN, TT and independent earthing systems.
From insulation and continuity checks to loop impedance, RCD and surge protection device testing, the KT66DL gives electricians a broad range of functions in one instrument. Its 3.5-inch colour display, on-screen connection guidance and advanced results memory help you work through testing and keep readings organised by distribution board, circuit and test type.

Why Choose the Kewtech KT66ET Bundle?
✓ Keep your testing equipment together
The earth spike kit fits inside the KT66DL carry case, keeping the bundle together between jobs. A padded neck strap and remote test probe add practical convenience during testing.
✓ Adapt to different installation testing requirements
The KT66DL offers both low-current and high-current loop options. Its two-wire ATT function is useful where a neutral is unavailable, such as lighting switch points and three-phase motor circuits. For low loop resistance measurements, the 25 A option delivers 0.001 Ω resolution on its 2 Ω range.
✓ Make readings easier to interpret and record
On-screen help shows the connections required for the selected function, while automatic RCD test results appear together on one screen. Advanced memory adds context to stored readings, including whether a result relates to Zs, Ze, R2 or R1+R2.
