Fluke LIQ-DUO-IE Industrial Ethernet Tester

Industrial network infrastructures pose unique challenges—from mixed connector types to harsh environmental conditions and mission-critical uptime demands. The LIQ-DUO-IE delivers the full capabilities of the LinkIQ Duo platform with added industrial-connector diagnostics and cable verification, enabling technicians to test, troubleshoot and document modern industrial-Ethernet cabling and network links.

Industrial Connector & Cable Support

• Includes support for RJ45 plus M12X, M12D and M8D terminations, enabling verification of industrial-Ethernet cables used in automation systems.

• Verifies performance from 10BASE-T up to 10GBASE-T (10 Mb/s to 10 Gb/s) for twisted-pair cabling, with wire map, length/fault diagnostics and performance test.

• Measures distance to fault (opens, shorts, mis-wires, split pairs) on industrial cables and identifies pair assignments for accurate mapping.

Network Switch & PoE Diagnostics

• Provides switch-port details, including switch name, IP address, port number, VLAN, and advertised data rate—useful for connectivity verification in industrial network segments.

• Performs PoE detection and load testing (Class 1-8) to verify that adequate power is delivered across the cabling infrastructure to powered devices.

Wi-Fi and Reporting (Duo Platform)

• While primarily targeted at industrial cabling, the Duo variant supports Wi-Fi analysis, including 2.4 GHz, 5 GHz, and, where approved, 6 GHz bands—helping evaluate wireless connectivity adjacent to industrial networks.

• Integration with LinkWare™ PC enables result logging, unified documentation, and export of test data for audit and acceptance workflows.

The Fluke LIQ-DUO-IE empowers network and automation technicians to carry a single tool that bridges structured-cabling, switch diagnostics, PoE verification, and industrial-connector testing. Whether deploying new industrial networks or maintaining existing ones, it delivers high-performance testing and documentation in one rugged package.
