- Multi-Function Network Cable Tester: Supports RJ45 (CAT5, CAT5e, CAT6, CAT6A, CAT7) and RJ11 telephone cables. Quickly detects continuity, short circuits, open wires, miswiring, and cable shielding status, ensuring your LAN or phone lines are correctly wired and ready to use.
- Fast/Slow Mode with LED Indicators: Switch between fast and slow scan speeds to identify wiring issues more precisely. LED lights on both master and remote units show wire order, making it easy to spot errors like open pairs or misaligned pins at a glance.
- Split-Type Design for Long-Distance Testing: Master and remote units can be detached and used separately, allowing you to test both ends of a long cable run, ideal for wall-mounted ports, long runs, or structured cabling. Perfect for home, office, or professional IT setups.
- Compact, Lightweight & Durable: Ergonomically designed with sturdy ABS housing, this pocket-sized tester is ideal for on-the-go network engineers, DIYers, and electricians. It’s your go-to toolkit for cable maintenance, upgrades, or new installations.
- Safe & Easy to Use: Simple one-button operation makes testing quick and hassle-free. LED indicators clearly show wiring status, while the G light instantly identifies shielded (FTP/STP) or unshielded (UTP) cables. Supports safe testing of telephone lines with typical voltages under 48-72V, ideal for both home and professional use.
