Velleman VTTEST11N kabeltracer en doorgangstester met toongenerator en versterkersonde

Network technicians and electricians often need to identify and trace cables hidden in walls, ceilings, or crowded patch panels. The Velleman VTTEST11N cable tracer combines a tone generator and amplifier probe in one kit, allowing you to locate wires, test continuity, and check telephone line status with ease. Its dual-tone output and long tracing distance make it suitable for both residential and commercial installations.

Why choose it

This tracer is a practical tool for anyone who works with low-voltage wiring. The transmitter offers single or dual tone output, helping you distinguish between multiple cables. The receiver's probe tip is sensitive enough to pick up signals through insulation, and the volume control lets you adjust the audio level to your environment. Its compact size and lightweight design make it easy to carry in a tool bag.

Ideal use cases

• Tracing network cables (Cat5, Cat6) in office buildings
• Identifying telephone lines and checking their status
• Testing continuity of wires and cables
• Locating breaks or shorts in electrical circuits
• Verifying polarity of telephone connections

Good to know

The VTTEST11N operates on standard 9V batteries, so you can easily find replacements. It does not include batteries, so be sure to have two 6F22 batteries on hand. The receiver's ergonomic design with a loudspeaker allows for hands-free operation when tracing over long distances. For best results, connect the transmitter directly to the cable under test using the appropriate connector.
