Fluke Networks LinkIQ™ Industrial Ethernet Cable+Wi-Fi+Network Tester

The Fluke Networks LinkIQ™ Industrial Ethernet Cable + Wi-Fi + Network Tester (LIQ-100-IE) is an advanced all-in-one testing solution designed to validate Industrial Ethernet cabling, troubleshoot wired and wireless networks, and deliver complete diagnostics for modern PoE-powered environments. Supporting speeds up to 10GBASE-T, it ensures accurate cable performance verification using frequency-based measurements, wire mapping, and fault detection, helping identify opens, shorts, and miswired pairs instantly.

Built for industrial automation and IT infrastructures, LinkIQ IE supports various Industrial Ethernet connectors including RJ45, M12X, M12D, and M8D—compatible with leading protocols such as EtherNet/IP, PROFINET, and EtherCAT. It offers switch diagnostics with detailed information on IP addresses, port/VLAN numbers, duplex modes, and advertised speeds, eliminating the need for additional devices.

For Power over Ethernet (PoE) environments, the tester is Ethernet Alliance Certified to IEEE 802.3af/at/bt standards and performs load tests up to Class 8 (90W), verifying that advertised power is actually being delivered. It also performs IP ping tests to check network connectivity and automatically detects connected switches, ensuring optimal network configurations.

Additionally, the Wi-Fi 6E analysis capability makes the LIQ-100-IE an extremely versatile tool, enabling detailed wireless network scanning by networks, channels, and access points. It detects overlapping APs, illegal channels, weak security configurations, and more, providing technicians with clear insights into potential Wi-Fi issues.

With its large color touchscreen interface, robust diagnostics, seamless integration with LinkWare™ PC software, and storage for up to 1,000 results, the LIQ-100-IE streamlines industrial network testing and reporting in one compact, rugged, and field-ready device.
