Description
Overview
- Portable locator for non-intrusive detection and depth measurement of buried pipelines, power and communication cables, and optical fibers. Model: HZ-4000A by Huazheng Electric.
- Transmitter with three connection modes: inductive, direct and clamp; suitable for varied site conditions.
- Receiver detects route, exact position, depth and induced current of underground pipes and cables; left/right and front/rear arrows plus dB readout for damage indication.
- External induction clamp for testing where direct connection is not possible; backlight for low-light operation.
- Optional GPS geolocation and professional data analysis software for automatic mapping and reporting.
- Integrated multimeter functions: output/line voltage, line current, impedance, power and continuity/insulation tests.
- Multiple positioning modes (valley/peak/broad peak/peak arrow) and complementary measurement methods to improve accuracy.
- Depth measurement methods: dual-level coil direct reading; single-level coil 80%/50% methods; 45 method. Receiver switches antenna mode and sensitivity automatically for depth readings.
- Strong anti-interference design measuring horizontal component, vertical component and horizontal gradient; transmitter output up to 10 W, continuously adjustable.
- Multiple selectable frequencies: transmitter frequencies include 128 Hz, 512 Hz, 1 kHz, 2 kHz, 8 kHz, 33 kHz, 65 kHz, 83 kHz; receiver supports radio and many passive frequencies (50 Hz, 100 Hz, etc.).
- Large-capacity lithium batteries for long continuous operation; rechargeable and can operate via adapter.
- Detection, inspection and maintenance of buried metal pipelines and coated pipelines.
- Locating faults and coating damage for power and telecom networks.
- Municipal planning, construction surveys and utility coordination.
- Model: HZ-4000A.
- Transmitter output power: up to 10 W, continuously adjustable.
- Transmitter frequencies (selectable): 128 Hz, 512 Hz, 1 kHz, 2 kHz, 8 kHz, 33 kHz, 65 kHz, 83 kHz.
- Receiver supported frequencies: radio, 50 Hz, 100 Hz, 128 Hz, 512 Hz, 1 kHz, 2 kHz, 8 kHz, 33 kHz, 65 kHz, 83 kHz.
- Transmitter connection modes: inductive, direct, clamp (external induction clamp included/optional depending on kit).
- Positioning modes: valley, peak, broad peak, peak arrow.
- Depth positioning: up to 6 m depending on model and ground conditions.
