The KT64DL Multifunction Tester has the feature set to test domestic and commercial installations and has a well-earned reputation for reliability, repeatability and ruggedness.

Kewtech’s loop circuits are all well designed to overcome noise, RCD uplift and contact resistance and the KT64DL is no exception.

The KT64DL is now a discontinued model but can still be purchased from a number of wholesalers and Kewtech distributors. The superseding model is the KT63PLUS.

Key Benefits

  • Easy to use with straight forward interface
