Noyafa Multi-Function Cable Tester for Continuity & Wiremap, PoE, Length Measurement, Port Flash, Color Screen & Rechargeable Battery NF-8504

The Noyafa NF-8504 Multi-Function Cable Tester is an indispensable diagnostic instrument designed for network engineers, cabling contractors, and IT professionals. Combining advanced wiremapping, precision cable length measurement, PoE detection, and port flashing, the NF-8504 accelerates network deployment and simplifies routine troubleshooting.

Comprehensive Testing & Fault Detection

Ensure cabling integrity on CAT5, CAT5e, and CAT6 network lines. The NF-8504 immediately verifies wire continuity, pinpointing opens, shorts, cross-connections, and split pairs. With its precision TDR-based length measurement, the device measures cables from 5 m to 300 m, identifying the exact distance to breaks or faults without guesswork.

Advanced PoE Diagnostics & Port Flash

Safely inspect Power over Ethernet installations. The tester supports standard IEEE 802.3af, 802.3at, and 802.3bt protocols, as well as non-standard PoE supplies from 5 V to 60 V, displaying polarity and operating voltage. When auditing complex patch panels, the Port Flash function triggers switch port LEDs across 10/100/1000 Mbps connections to rapidly trace cables and determine duplex modes.

Durable Design Built for the Field

Equipped with a bright 2.4-inch full-color LCD screen, test readouts remain crisp and readable even in dim server closets. The unit includes up to 60 V anti-burning circuit protection against unexpected live line voltages. Powered by an internal 1500 mAh lithium battery with modern USB Type-C charging and an auto-off timer, the NF-8504 is always ready for demanding workday operations.
