TDR-420 is a hand held Time Domain Reflectometer designed to identify and locate faults in power, telecommunications and teletechnical cables. TDR-420 reflectometer allows to measure the length of the cable and determine the distance to damage or impedance variation in the range of 4 m to 6000 m in conductors with metal wires. The shortest measuring range of 7 meters and a dead zone of 0.6 meters allows to locate damages at a very close distance from the place where the device is connected.

Two cursors allow to determine the place of two damages simultaneously and the distance between them.

Thanks to the color 3,5” TFT display with a resolution of 320 x 240 pixels, the indication of the location of the damage is precise and the results easier to interpret.

Difficult environment conditions during measurement work are frequent problems encountered by electric installers and maintenance services. Thanks to the unique housing TDR-420 ensure a degree of protection on IP67 level, what means dustproof and protection against water penetration during short-term immersion. Therefore, working in very dusty terrain or accidental contact of the device with water will not affect the correct operation of the reflectometer.
