The HZ-4000 underground cable and pipe locator can accurately location and measure the buried depth of underground pipelines, cables, and optical cables without excavation, and accurately find the location of the damaged point of the outer anti-corrosion layer of the underground pipe and the fault point of the buried cable. and is suitable for various underground The detection and inspection of metal pipelines, pipeline management and maintenance, municipal planning and construction, power supply and other departments are the necessary instruments for pipeline maintenance units.
Multiple Functions
Transmitter: Supports three connection modes – inductive connection, direct connection, and clamp connection – to suit different field applications.
Receiver Functions: Detects the position, path, depth, and tube current of underground pipes and cables.
Intuitive Positioning: Left and right positioning arrows quickly and accurately indicate the target pipeline position. Front and rear arrows, along with dB value indication, pinpoint the location and size of coating damage.
Backlight Display: Equipped with a backlight for convenient use in nighttime or low-light conditions.
GPS Geolocation (Optional): Supports GPS geolocation with automatic pipeline mapping.
Data Analysis Software (Optional): Professional software enables automatic detection report generation.
Unique Feature of HZ-4000: Locates breakdown points (pipeline breakdowns refer to coating damage points; electric cable breakdowns refer to outer layer damage). Detects insulation damage of underground pipes and cables.
