  • LinkIQ (LIQ-100, non-Duo) Model: LIQ-100

    Cable, network and PoE testing without Wi-Fi analysis.

    Industrial Ethernet installs.

Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • The plain LinkIQ-100 omits Wi-Fi; only the Duo analyzes wireless networks.
  • IE models are for industrial connectors, not a standard office upgrade.
  • FPC3 Gold bundles add premium care, not different hardware.

Why people pick it

  • Qualifies cable to 10 Gb/s with IEEE frequency-based measurements, not just a link test, per Fluke Networks
  • Nearest-switch diagnostics and ping built in, so one device covers both cable and network layers
  • Certified PoE load testing up to class 8 for 802.3bt camera and AP installs
  • Duo model adds 2.4, 5 and 6 GHz Wi-Fi surveys without carrying a separate tool

Know before you buy

  • Wi-Fi analysis is on the Duo model only; the standard LinkIQ omits it
  • 6 GHz support depends on country approval
  • Industrial M12/M8 connector testing requires the separate IE models
  • Substantially more than a basic continuity tester; heavy for casual home checks
