Extech CT20 continuity tester is the perfect tool for electricians, cable TV and
audio system installers, technicians, carpenters, handymen, and do-it-yourself
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
