Hioki 3665-20 LAN cable tester

The Hioki 3665-20 LAN cable tester provides wire map, shield test, cable length, wiring direction for up to 21 pairs and cable length, and is compatible with Cat 6.

The tester is intuitive — plug the cable in and the tests commence, checking all parameters and displaying test results at a glance (split pairs, transposed pairs, reversed opens and shorts).

Up to 21 terminators can be connected (additional terminators sold separately.) This is convenient for confirming the connection destinations of multiple cables and avoids having to go back and forth to change terminators.

The tester is designed to measure for cable length and detect the location of broken or short-circuited wires to an accuracy of ±4% of reading ±1 m. The Hioki 3665-20 meets safety standard: EN61010 pollution level 2 and EMC standard: EN61326.
