Network Cable Tester 

Multifrequency pulse transmission format – ensures stable signal propagation over long distances with strong anti-interference against magnetic fields and external noise.

3km+ transmission distance – allows cable tracing and fault location across large buildings, campuses, or outdoor installations without signal loss.

8Vp-p signal output level – delivers powerful, easy-to-detect signals even on long or loaded cables for accurate positioning.

Three cable types supported (network/telephone/BNC) – one tool for RJ45 Ethernet, RJ11 telephone, and coaxial lines, reducing equipment needed on-site.

Cable short circuit and wire break judgment – quickly identifies open circuits and shorts to speed up troubleshooting and repair.

Network line to line testing – verifies continuity and pin-to-pin mapping for twisted pair cables.

Shielded network cable test capability – works with shielded (STP/FTP) cables without interference from the shield itself.

Strong anti-interference design – operates reliably near motors, power lines, or other electromagnetic noise sources common in industrial environments.

Split transmitter/receiver design – allows one person to trace cables from end to end, with the receiver remaining portable and lightweight (80g).

Adjustable sensitivity on receiver – fine-tunes detection range from broad cable bundles to pinpointing individual wires in dense panels.

Headset function (included) – enables audible tracing in noisy environments so you can hear the tone clearly without disturbing others.

Built-in floodlight (lighting function) – illuminates dark server rooms, crawl spaces, or junction boxes for hands-free visibility.

Low voltage prompt – alerts user when the 9V battery is low to prevent unreliable testing or interrupted work.

Automatic shut-down after 30 minutes – preserves battery life when the tester is accidentally left on during breaks or between jobs.

Lightweight and compact design – transmitter (84g, 145×56×28mm) and receiver (80g, 175×45×25mm) fit easily in tool pouches or pockets.

Complete accessory kit included – comes with headset, RJ11 adapter, RJ45 adapter, and alligator clips, ready to use out of the box.

Works on live or unloaded cables – accurately locates and tests cables regardless of whether they are powered or disconnected.

Fast and accurate line checking – quickly identifies network lines, telephone lines, and coax with precise positioning even on loaded circuits.

Orange body color – highly visible on cluttered workbenches, dark floors, or cable trays to prevent misplacement.

Transmitter low operating current (≤20mA) – extends battery life even during extended cable tracing sessions.
