Kewtech KT65DL Digital 8-in-1 Multifunction Tester

The Kewtech KT65DL is an advanced 18^th edition 8 in 1 multifunction tester designed specifically for the UK market. Its robust construction includes a protective hard cover to protect the face of the KT65 when not in use. A large soft carry case is also included to carry the tester and accessories.

The KT65DL, one of the most advanced multifunction tester from Kewtech, carries out continuity, insulation, loop and RCD testing in accordance with the latest 18^th edition regulation. The KT65 also includes test modes for volts, phase rotation and earth testing when used in conjunction with the optional earth spike test kit.

PAT testing with the Kewtech KT65DL

The Kewtech KT65DL can also be used as a PAT tester when used in conjunction with the Kewtech PAT ADAPTER1 (available separately) for Class 1 and Class 2 testing. Extension leads can also be tested with the Kewtech R2, providing a wide range of PAT testing options. PAT results can be saved to the tester and downloaded at a later date with the included software. Auto ID advance is also included to make PAT testing even easier.

Building on the already impressive KT63 and KT64 multifunction testers, the Kewtech KT65 also has 55V loop test facility for testing 110V CTE on-site system and also 0.001 ohm resolution high current loop test for great accuracy. Phase rotation is also included for testing 3 phase machinery and checking that phase rotation is correct.
