Introduction
With a split and rugged design, we made T8 to be one of the world's most portable and powerful cable fault locators. We built in kinds of time-domain reflectometer(TDR) methods to pre-locate faults, like LV(low-voltage) TDR , Arc Reflection Method(ARM, optional), Impulse Current Decoupling method(ICE).For multiple types of cable faults.
All parts can be used independently. You can only use our TDR part to test the length of a cable, or can only use Pinpointer to locate a fault while you already have a surge generator
Fault location surge generator, model LP15/8
Cable fault pre-locator (TDR), model WL20
Cable fault pin-pointer, model PP20
Work together, easy to use T8 to locate cable faults

Work smarter: all parts can work independently
