Product OverviewviewThe HM9800 pipeline detector is a powerful tool designed to locate and determine the depth of underground cables, optical fibers, and metal pipelines. It is ideal for use in various industries such as mobile communications, telecommunications, power, cable TV, water supply, gas, and more.
With its real-time automatic gain and manual gain features, the HM9800 provides clear signals, peak detection, direct sounding, and DC value readings, making it user-friendly and efficient. It also includes an outer sheath fault location function, allowing the transmitter to output a 4.8Hz fault frequency for precise identification of cable sheath faults.
The optional accessories like "signal probe and tracer line" enable the detection and localization of non-metallic drainage pipes, expanding the device's versatility. The system automatically selects the optimal search frequency, measures loop resistance, and performs continuous impedance matching to ensure the best signal quality.
The receiver can detect both passive and active frequencies, with automatic real-time gain adjustment, directional indicators, and other intelligent features, making it one of the easiest locators on the market to operate.
