Professional Continuity Tester
Audible and Visual Indicator
The CT20 continuity tester features a bright flashing LED and loud pulsating beeper to indicate local continuity making it ideal for use in environments where excessive noise is present.
Remote Continuity Feature
With the use of the included remote probe, the CT20 does not tie-up two people when identifying and labeling long distance wire/cable runs.
Flashing Remote Probe
The CT20’s flashing remote probe with its two lead, bi-color LED light allows a single user to identify up to three wires or cables at a time for correct labeling – requiring only one trip to the end destination. This reduces time spent going back and forth between locations.
Polarity Verification
The CT20 continuity tester sends a 20mA DC current pulse through the wire or cable under test to the bi-color remote probe, allowing the technician to identify each of the wires under test and eliminating the possibility of false high impedance readings.
Use in the Home
The CT20 Remote & Local Continuity Tester's many features can assist homeowners to complete numerous tasks – everything from the identification and labeling of new home wiring to the installation of a comprehensive home entertainment system.
Industrial and Commercial Applications Made Easy
Thanks to the CT20’s remote probe, Extech’s robust continuity tester is perfectly suited for testing continuity in environments that require the use of lengthy cable runs, as found in the industrial and manufacturing sectors.
