The NF-308S Wire Tracker is a professional tool used to test, trace, and also locate faults in different types of cables. It is ideal for electricians, network installers, and aslo IT professionals who need to find cable breaks, miswires, or identify cable paths.
Whether you're working with Ethernet (RJ45), phone lines (RJ11), or also coaxial cables, the NF-308S makes the job faster and easier.
The NF-308S helps you find common cable issues such as:
Firstly, Open circuits
Secondly, Short circuits
Also, Crossed or miswired pairs
Lastly, Split pairs
As a result, you can solve problems faster and also keep your systems running smoothly.
This device includes a transmitter and also a receiver. The transmitter sends a signal through the cable. Then, using the receiver (probe), you can trace the cable path—even if the wire is hidden behind walls or also inside a bundle.
This makes it easy to identify where each cable leads or to locate one wire among many.
The transmitter has a large LCD screen that clearly shows cable type, test results, and also wire map details. It’s easy to read in any lighting, so you can work comfortably on-site or in low-light areas.
The NF-308S is compatible with:
RJ45 Ethernet cables (Cat5, Cat6)
RJ11 telephone cables
Coaxial (TV and CCTV cables)
Some models may include adapters for USB, BNC, or alarm wires
Because of this, it's a great tool for both network and telecom jobs.
The tester includes remote ID units, which let you test cables from both ends—perfect for long cables or cables in different rooms. This helps save time, especially when you're working alone.
The NF-308S also supports cable length testing, using Time Domain Reflectometer (TDR) technology. This lets you estimate the length of the cable or the distance to a fault, helping you pinpoint issues faster.
Even beginners can use the NF-308S. The buttons are clearly marked, and also the on-screen display guides you through each test. So whether you’re a professional or a DIY user, it’s simple to operate.
The unit is powered by a standard 9V battery (usually not included). It’s lightweight, compact, and also easy to carry in a tool bag or pocket. That means you can use it anywhere—on-site, in the field, or at the office.
