NOYAFA NF-B509 Wire Tracker + Digital Multimeter – PoE, Port Flash, NCV

The NOYAFA NF-B509 combines a network wire tracker with a digital multimeter in one English-UI kit. Trace and continuity-check RJ45 runs, measure cable length, verify PoE pins and voltage, then flash the live switch port—before switching to AC/DC voltage, current, resistance and NCV for electrical checks.

Menus cover SCAN, CONT, Length, PoE, Flash and Multimeter. The colour LCD keeps results readable on site; the tone receiver with sensitivity control helps hunt cables in walls or bundles. Built for installers who want cable and meter tools without swapping gadgets.

FAQ

Is this the NF-8504 or NF-859GT?

No. This SKU is the NF-B509 only (EKO-NF-B509). Those models are separate and are not included.

Does it include a multimeter and PoE test?

Yes. Multimeter modes cover AC/DC voltage, DC current, resistance, continuity and NCV; PoE identifies powered pins and shows voltage. Port flash helps find the switch port.

What cable length can it measure?

RJ45 length is about 5–200 m (±3 m per listing). Continuity/scan range is longer for tracing.

Is this the same as the NF-8601 / NF-308?

No. This is the NF-B509 tracker + multimeter only. Do not treat it as NF-8601, NF-308 or other Noyafa cable testers.

Is UK delivery free?

Free UK delivery. Dispatched in 1–2 working days, delivered in 5–7 working days. Price incl. VAT, VAT invoices available.
