Fiber optic fault locator HZ-4000E

for cables

The HZ-4000E Underground Cable Fault Detector is designed to accurately locate underground pipelines, power cables, and optical fibers, as well as to measure their buried depth without excavation. It can precisely identify coating damage points on metal pipelines and fault points on buried cables.
 This instrument is widely used in underground metal pipeline detection, pipeline maintenance, municipal planning and construction, and power supply departments. It is an essential tool for pipeline operation and maintenance units.
