## Features

- 🌹【10-in-1 All-in-One Network Tool】ZHOUCE NF-859GT integrates 10 functions—cable testing, optical power meter, NCV, POE power supply detection, and more—into a single device. — Supports RJ11/RJ45 (CAT5e/CAT6/CAT6a) cable and telephone line continuity testing, 10M/100M/1000M device POE testing (including supply voltage and polarity detection), port flashing location, and cable length measurement. The receiver features newly upgraded dual red test probes for smoother operation.
- 🎁【7-Wavelength Optical Power Meter】 Directly covers 7 common wavelengths: 850/1300/1310/1490/1550/1625/1650 nm. Power detection range spans -70 to +10 dBm, delivering precise optical signal strength measurements. Integrated fiber continuity testing paired with POE detection streamlines cabling and maintenance in one step.
- 🌹【POE + Network Cable Dual Detection】The ZHOUCE NF-859GT is specifically designed for POE switches and routers, quickly determining POE power supply status, voltage compliance, and polarity accuracy. It also precisely identifies faults like continuity, short circuits, and cross-wiring in CAT5/CAT6 cables. Non-contact NCV + 1500mAh lithium battery + LED light ensure reliable operation in dark environments, server room cabling, and other complex scenarios.
- 🎁【Dual Red Test Leads】650nm standard wavelength with fast/slow flash modes ensures stable precision. The receiver includes this functionality, supporting: ST/SC/FC cable continuity testing. Combined with POE and network cable testing, it offers portable convenience.
- 🎁【Port Flashing Location】When connected to a POE device, the NF-859GT synchronizes port indicator flashes. The screen displays port speed and duplex mode, even pinpointing POE-powered ports. No more running back and forth to locate cables or ports—identify them instantly.
- 🎁【Cable Length Detection】Measures Ethernet cable lengths from 2.5 meters to 200 meters. Ideal for IT cabling projects and locating cable breaks. Accuracy remains stable with longer cables, with an error margin of only ±0.5%. Combined with POE testing, it helps preemptively avoid power attenuation issues in long-distance cabling
- 🌹【Cross-Model Compatibility】Whether paired with the NF-859GT or NF-859GK receiver, it works seamlessly with multiple transmitter models including NF-859GE, NF-859GH, and NF-859GS. No need to purchase an entirely new set—existing tools remain compatible. Fully supports POE, optical power, and network cable testing functions, preventing equipment idleness and unnecessary duplication of expenses.
- 🌹A Practical Gift for Everyone The perfect thoughtful present for friends and family, network engineers, IT operations specialists, and low-voltage installation professionals! Versatile functionality + portable design—useful on the job and handy for everyday tasks. Ideal for holiday gifts or workplace perks. Customer service responds within 24 hours.
