Lowest Cost Full Specification  Professional Graphical TDR!


The Pro400 Graphical TDR is a great tool for locating faults in metallic cables with 2 or more conductors. Twisted pair, coax, LAN cabling, 2-wire irrigation control cable, etc. are simple to test for distances to shorts, opens, etc. By connecting the leads to the cable to test a graphical display quickly and clearly shows faults and ‘events’ on that cable along with the distance.

In addition, the Pro400 transmits a standard analog tracing tone for use with common tone probes to find the termination point of a cable. Features of the Pro400 include backlit display, auto off, calibration of Vp from 20 to 99%, 3 cable impedance level options, an extremely small 2 foot dead zone, and water/dust protection. The Pro400 is a big bang-for-the-buck product!
