* 【High Quality & Durable】Made of high quality material, durable, wear-resistant, corrosion resistant. Normal gain is 30dB and input impedance is nominal 100M ohm
* 【Measurement Category】Measurement area includes line tracking, short circuit testing, clearance/busy/ringing recognition. For non-terminal cables, the clamp mode can be used not only to measure directly but also to measure phone and network lines. Built-in speaker in the probe
* 【High Efficiency】 Volume adjustable professional wire and toner probe kit with sound source, you can identify and track wires and cables in groups without damaging insulation
* 【Accurate Test】Optional continuous or adjustable generator makes the method simple and accurate test results. It is widely used in cable and wire maintenance
* Prevents Short Circuit of Conductors: The circuit tester has a spring-loaded ON/OFF button. Adjustable volume sensitivity control Resistant carbon fiber plastic tip to prevent accidental short circuit when detecting wires. Insulation probe and built-in speaker effectively avoid short circuit of conductor, more safe to use
