All-in-one Network Cable Tester
Add NF-8209S to your toolbox and fix all ethernet issues easily. Start wiremap checkup, path tracking, length measure for network cables. Locate ports on ethernet switch or router and run link test.


Check Cable Continuity
Plug and test open, short, cross, etc. for RJ45 ethernet cables.
RJ45 Length Meter
Measure the length of 8 wires of a network cables with 99% accuracy.
- Supported test range: 8.2 - 1,640ft / 2.5 - 500 meters.


Cable Scanning
Anti-interference mode and normal mode can be switched at will, and are widely used in engineering wiring, equipment room maintenance, equipment update and other scenarios.
Crimp Test for RJ45 Connector
Plug in an RJ45 cable into the QC port and quickly run a crimp test. Identify any wiring issue of the connector.


Port Blinks
Connect a working ethernet cable to the Flash/PoE/Length port. Or connect a wall ethernet port via a testing cable. Locate the corresponding port on a switch via the flashing light at the same frequency.
Link Test
Automatically perform link test while the port blink function is in progress.


NCV Induction Pen
Hover over objects, electric components, and surfaces. Tell immediately when an object contains electricity.
USB Type-C Charging
Equipped with a 1,400mAh polymer lithium battery, NF-8209S suports a long working time with Type-C recharging.


Two-Color Injection Molding
The inner layer is a hard shell, sturdy and resistant to failing, and the outer layer feels comfortable.
Sensitivity Adjustable
Based on different situations, adjust the sensitivity of the probe. Find the cable accurately even among messy cables.


Focus on Details
High standard RJ45 interface. Translucent Silicone combined mode light. Condenser lens LED flashlight. Adjustable sensitivity knob.
