IRG 400 Portable Time Domain Reflectometer
The IRG 400 is compact and powerful time domain reflectometer for cable fault pre-location that provides fast and precise measurement results on single or multi-phase cables.
The choice is yours, as the IRG 400 is available as a portable device in a transport case or as a 19″ plug-in unit in the Syscompact 400 and Syscompact 400 Portable. This provides maximum flexibility and is the solution for a wide range of applications for precise cable fault location.
The IRG 400 can be operated using a tablet or laptop. Operation is extremely efficient when used in combination with the tried-and-tested BAUR Software 4 (laptop) or the new touch-based BAUR BUI-F application (tablet). Connection can also be established over WiFi, thus enabling you to perform galvanically isolated measurements outside of the HV area for increased safety. An integrated separation filter allows TDR measurements to be performed on live cables up to category CAT IV / 600 V.
Built into a rugged Pelicase housing, this TDR can be used in the most extreme field conditions. Recorded measurement results can be exported via USB interface.
