Kewtech KT66DL 12-in-1 Multifunction Tester
The Kewtech KT66DL 12-in-1 Multifunction Tester is built for maximum reliability and ease of use, offering a comprehensive suite of features vital to the everyday contractor. The ultimate tester, the KT66DL comes complete with a pioneering loop testing system which includes both 2 & 3 wire low current test options, and Anti-Trip technology (ATT) for no trip LOOP L-PE testing on all RCDs. The 2-wire option is especially useful in cases where no neutral wire is present, for example in 3-phase motor lines or testing at switch points for lighting circuits. Beyond Loop testing, the illustrious KT66DL also provides an in-depth RCD testing facility now with the the ability to test EV charging points when used in conjunction with the Kewtech KEWEVSE adapter. Together these features combine to create an MFT with a level of performance and accuracy like never before.

The full specifications of the Kewtech KT66DL 12-in-1 MFT are detailed below.
High-Quality Design
The intuitive user interface of the KT66DL MFT is comprised of a single rotary dial, four tactile function softkeys and a 3.5 inch LCD dot matrix display. This screen shows information simultaneously, presenting the operator with all auto-tests at once without the need to navigate multiple menus. The three methods of testing with the KT66DL are single button press, lockdown test button for continuous testing and the alternate test button featured in the additional probe. Assign the type of test, circuit number and DB to test results for storage within the advanced memory of this MFT. A useful help option is also included within the unit, explaining exactly how to connect the instrument according to the selected function. In addition to a lid for extra protection, this Kewtech model is supplied with Kewtech's highly popular G7 test leads, a robust soft carry case, printed manual and end of the line calibration certificate. Rated CAT IV 300V and CAT III 600V, the KT66DL is fully in line with the latest IEC safety guidelines.
Kewtech KEWEVSE EV Charging Point Adapter
Combine the Kewtech KT66DL 12-in-1 Multifunction Tester with the compact Kewtech KEWEVSE Adapter for access to a range of additional testing features. With this EV Charging Point adapter attached to the KT66DL, the operator can simulate the presence of an electric vehicle, perform a 6mA DC RCD test and much more.
