Meet the LinkIQ Duo from Fluke Networks
When you’re on site, you don’t have time for multiple tools, second guesses, or incomplete data. Whether you’re commissioning new infrastructure or troubleshooting an issue under pressure, you need fast, reliable answers.
That’s where the LinkIQ Duo changes the game.
Combining cable testing, network diagnostics, and Wi-Fi analysis in one rugged device, LinkIQ™ Duo delivers a complete picture of your network environment—quickly, clearly, and without the usual complexity.
Cable testing you trust. Network visibility you need.
At its core, LinkIQ validates cable performance up to 10Gb/s, giving you confidence that your infrastructure can support the demands placed on it. Using frequency-based measurements and a full wire map, it quickly identifies faults like opens, shorts and miswires along with the exact distance to the issue.
See beyond the cable
LinkIQ Duo brings powerful network diagnostics into the same tool, allowing you to verify connectivity and understand what’s happening on the network without reaching for additional equipment.
With built-in ping testing and nearest switch diagnostics, you can instantly see key details like switch name, port number, VLAN, and available data rates. It’s everything you need to validate configuration and identify issues—right there in your hand.

Key Features
Wi-Fi 6E ready
With the Duo model, you also gain visibility into the wireless environment, including networks, channels, and access points across 2.4, 5 and 6 GHz bands. This means faster troubleshooting, better planning, and a clearer understanding of how your wired and wireless infrastructure work together.
Built for industrial networks
For industrial environments, LinkIQ supports key protocols including EtherNet/IP, PROFINET and EtherCAT, with compatibility across common industrial connectors like M12 and M8. This makes LinkIQ just as effective on the factory floor as it is in commercial IT environments and ideal for teams working across both.
Verified Power over Ethernet
PoE can be a hidden source of problems but LinkIQ easily removes uncertainty by detecting PoE class and also performing load testing to confirm that the expected power is actually being delivered. It’s the simplest way to avoid costly surprises during installation or troubleshooting.
Designed for the real world
A large, gesture-based colour touchscreen makes LinkIQ intuitive to use from the moment you pick it up. Results are displayed graphically, so issues are easy to understand at a glance. Add in features like cable toning, port blink, remote identifiers and result storage, and you’ve got a tool that’s built to make technicians faster and more effective on every job.
One device. Less downtime. Better outcomes.
Instead of switching between testers, chasing partial answers or making return visits, LinkIQ Duo gives you everything you need in one place. Faster testing, faster troubleshooting and more confidence in every result.
