ND-8643 Underground Pipeline Detector

Product Introduction

       The ND-8643 is a high-performance underground metal pipeline detection system, consisting of a signal transmitter and receiver. It can be used for path detection, pipeline survey, and depth measurement of metal pipelines and underground cables. With various optional accessories, it supports identification through three methods: intelligent clamp identification, clamp current measurement, and stethoscope identification. It can also locate pipeline insulation damage and certain types of cable faults.

Product Features

☆ Compass Display: Intuitively shows pipeline position.
☆ Left/Right Indication: Left and right arrows indicate pipeline location.
☆ Tracking Accuracy Prompt: Under certain frequencies, real-time measurement of pipeline current direction enables tracking accuracy prompts and eliminates interference from adjacent lines.
☆ Real-time depth and current measurement.
☆ Historical Curve Display: Visually shows signal changes.
☆ Identification: Clamp (optional) identification provides clear results; stethoscope (optional) identification is used when clamps are inconvenient.
☆ Ground Fault Location: Using an A-frame (optional), it locates insulation damage points to ground without zero adjustment, with arrows indicating fault direction.
☆ Fully digital high-precision sampling and processing, with an extremely narrow receiver bandwidth and strong anti-interference capability, effectively suppressing power frequency and harmonic interference from nearby cables and pipelines.
☆ Multiple detection frequencies: Active and passive detection.
☆ Transmitter offers multiple signal output methods: Direct connection output, clamp coupling, and radiation induction.
☆ High-power transmitter output, multi-level adjustable, automatic impedance matching, and full protection.
☆ Built-in high-capacity lithium-ion battery pack, automatic shutdown under low voltage, and automatic shutdown after prolonged inactivity.
☆ Rugged and lightweight housing for easy portability.
