Overview
Enviro Test Construct portable cable fault locator with TDR, & surge generator with a split and rugged design, we made this product to be one of the world’s most portable and powerful cable fault locators. We built in kinds of time to domain reflectometer (TDR) methods to pre to locate faults, like LV (low to voltage) TDR, Arc Reflection Method (ARM), 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 Pin pointer to locate a fault while you already have a surge generator.
