Continuity Testers
Continuity testers check that a copper cable run is wired correctly end to end, confirming pins and pairs before a link is trusted for live traffic.

Continuity Testers confirm that a copper cable run is wired correctly from end to end before it is trusted for live traffic, checking that every pin and pair reaches the right place. They are a day-to-day tool for installers verifying patch leads and fixed cabling on site.
What to look for
- Tester type: choose LAN continuity for basic wiring checks, PoE for power detection, or a network qualifier for more detail.
- Several kits here include a separate PoE checker alongside the main continuity tester.
- Remote kits numbered 1 to 12 let you test multiple cable runs and identify each one by number.
For full certified test results rather than a pass or fail check, see LAN Cable Certifiers or Cable Qualifiers. To trace a cable run through walls or trunking, see Cable Tracers, or browse the full range under Copper Testers.
Continuity Testers FAQs
What does a continuity tester check?
It confirms that every pin and pair in a copper cable run is wired correctly from one end to the other, catching miswires, opens and shorts before the cable is put into live use.
Do I need a separate PoE checker?
Several kits in this range include a separate PoE checker alongside the continuity tester, useful for confirming Power over Ethernet is present on a link as well as checking the wiring itself.
What are the numbered remote kits for?
Remote kits, such as the RJ45 socket style set numbered 1 to 12, let you test and identify multiple cable runs at once, which speeds up checking a full patch panel or floor box installation.
