The LFG-50 / LFG-200p & PT-14 Tracer:

The LFG-50 and LFG-200P are portable low-frequency generators designed for locating and tracing underground utilities, including power cables with metal cores and metal pipes. Paired with the PT-14 Tracer, they form a powerful system for route tracing, short-circuit detection, and cable identification in complex environments.

Both generators feature automatic load impedance matching, overload protection, and multifrequency operation for maximum flexibility. The LFG-200P is also available as a built-in option in ETL-series Cable Fault Locators, making it a seamless addition to vehicle-based testing systems. The PT-14 Tracer ensures fast and accurate cable detection, defect identification, and depth measurement, enabling precise mapping of underground infrastructure.
