The CT20 is an electronic tool for electricians, alarm, cable installers and others who routinely need to check circuits for continuity and also identify cables and wires. It allows a single user to quickly identify and label two wires even when the wire ends are located in different rooms. It can accommodate test wire lengths up to 10,000-feet (3,000 meters), 26-gauge minimum. The CT20’s Remote Continuity mode allows the user to check continuity and to identify two or more cables/wires simultaneously.

� A bright flashing LED and loud pulsating beeper indicate local continuity

� Remote continuity with the use of the remote probe

� Flashing remote probe - two lead, bi-color (red/green) LED probe allows a single user to identify up to three wires or cables at a time

� Lightweight and pocketsized, clips on and hangs from the cable(s) under test without falling off

� Great for Electricians and Helpers, Cable TV and Audio System Installers, Alarm Technicians, Plumbers, HVAC Installers etc.
