2-in-1 Cable Tester Mapping/Continuity

CT055B

Extreme compact RJ45 network cable tester. Lightweight, easy to carry, and cost-saving. Fundamental pair-to-pair and grounding continuity tests solve over 90% of cable wiring problems, e.g., short, open circuits, and miswiring. Substantial port mapping and unique resistance measurement further offer value-adding functions which only offered by top-end testers on the market. A coupler and an additional patch cable are included in aid of detecting ports that have an RJ-45 plug (MPTL for instance) at the remote end.

Product includes:
 Tester main unit x 1 (AA battery sold separately)
 Remote plug x 1
 Port mapping plugs #1-8 x 1 set
 Female to female shielded RJ-45 coupler x 1
 Shielded patch cord x 1

2-in-1 Port Mapping/Continuity Cable Tester
