Network Cable Tester and TDR

Jonard Tools TDR-100 Network Cable Tester and TDR The Jonard Tools TDR-100 is a versatile, field-ready tester that combines a time-domain reflectometer (TDR) with a standard network cable tester. Designed for network engineers, IT professionals, and low-voltage technicians, it quickly identifies cable faults, measures cable length up to 400 m (1,312 ft), and traces installed cabling with an integrated tone generator. The 2.5″ color LCD and built-in flashlight ensure clear readings even in dimly lit patch panels or conduit runs.
