Megger TDR1000/3 Time Domain Reflectometers, 5km

This time domain reflectometer from Megger puts cable fault detection in the palm of your hand. It works by transmitting a signal to your conductor and listening for fault-indicating reflected sound waves in return. Any reflections are clearly displayed on the TDR's screen for fast, accurate error diagnosis. Getting started is a snap thanks to an auto set-up feature, and the dual-cursor switch gives you full control over operations. This versatile tool is designed to work with all metallic cable pairs in a maximum range of 5km.
