Measure, trace, and troubleshoot with unshakable confidence using the Klein Tools 501-915 TDR cable length meter an ultra-precise, multi-function powerhouse built for pros who demand speed and accuracy on every job. Designed to measure electrical, data, two-wire, and Romex cables up to an impressive 3000 feet, this device uses advanced Time Domain Reflectometry (TDR) technology to pinpoint the exact location of opens, shorts, or faults even on unterminated lines.
Preloaded with accurate Velocity of Propagation (VoP) values for coax, data, and multiwire cables, and boasting a margin of error within just 2% plus 3 feet, this tool delivers dependable results every time. From clean installations to fast diagnostics, this meter shines with user-friendly performance. The full-color, interactive LCD and intuitive interface streamline cable testing, while the built-in tone generator (probe sold separately) makes tracing open-ended, unenergized wires simple.
Switch easily between imperial and metric units, save custom VoP profiles for repeat jobs, and connect with ease using the included coax-BNC, RJ45 jack, or premium alligator clips. Complete with test leads and a padded carrying case, the 501-915 cable length meter is the smart, rugged companion for electricians, low-voltage techs, and datacom installers alike. For over 165 years, Klein Tools has built a reputation for delivering rugged, high-performance tools trusted by professionals across the trades.
