Extech CT20 Continuity Tester

Description

The Extech CT20 continuity tester is perfectly suited for checking local continuity, remote continuity,
and polarity. Easy to use and accurate, the Extech CT20 continuity tester is the perfect tool for
electricians, cable TV and audio system installers, technicians, carpenters, handymen, and do-it-yourself
homeowners. The Extech CT20 continuity tester uses using a bright flashing LED and loud pulsating beep to show
continuity. A remote probe is included to eliminate the need for two people when identifying and labeling
long-distance wire/cable runs. The Extech CT20 continuity tester’s remote probe allows a single user to
identify up to three wires or cables at a time for correct labeling with only one trip to the other end
location – cuts down on multiple trips back and forth. Polarity can be verified with the Extech CT20
continuity tester via a 20mA DC current pulse through the wires to the remote probe; this enables the
technician to identify each of the wires under test at the other end of the cable run and eliminates the
possibility of false high impedance readings. The Extech CT20 continuity tester is lightweight and pocket sized and clips onto and hangs from the cable(s)
under test area without falling off and comes complete with a remote probe, test leads with alligator clips,
9V battery and pouch.
