The Armada Technologies PRO220K Advanced Wire Identification Kit helps you identify the termination point of a wire among a bundle of wires, a task which can be difficult and time consuming if you don’t have the right tools. The PRO220K Advanced Wire Identification Kit identifies unknown wires in seconds. The Pro220K utilizes a powerful PRO110 Tone Generator to send a tracing tone down the wire, while the user employs the PRO210F Advanced Tone Probe at the termination point, listening for the loudest signal emanating from a wire. By finding that tone, the user is identifying the wire in question. The PRO220K uses inductive forces to sense the signal without the need to actually touch the wire. The PRO210F Probe offers the latest in AC noise rejection technology, actually ignoring random signals not associated with the PRO110 Tone Generator. Additionally, the PRO210F Probe incorporates an LED headlight for the all-too-often dark working environments. The AA battery power means the PRO220K lasts longer than most other tone and probe kits.
