Product OverviewViewThe HM9800 pipeline detector is designed to locate and determine the depth of underground cables, optical fibers, and metal pipelines. It is ideal for use in mobile communications, telecommunications, power, cable TV, water supply, gas, and other utility sectors.
The HM9800 offers both real-time automatic gain and manual gain settings, along with peak signal display, direct sounding, and key DC value features, 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 accurate detection of cable sheath faults.
Optional accessories like the "signal probe and tracer line" can be used to detect and locate non-metallic drainage pipes. The system automatically selects the best search frequency, measures loop resistance, and performs continuous impedance matching to ensure optimal signal output. The receiver supports two passive and two active frequencies, with automatic real-time gain adjustment, left-right direction indication, and intelligent operation features, making it one of the easiest locators on the market.
