Underground pipeline detector SL-400

Underground pipeline detector Model: SL-400 Instrument: Product Overview SL-400 wide range of underground pipeline detector, the need for precise determination of underground metal pipe and cable location, direction and depth distribution of industries and sectors, such as construction , municipal construction, public utilities, electricity, geology, exploration, petroleum, railway, communication, etc., which are essential special tools. Second, the characteristics ★ be commenced frequency and radio frequency positioning; ★ induction method to detect, without connecting line between the transmitter and the signal line, so that the transmitter is not placed restrictions on field conditions, increase the flexibility of the instrument used; ★ detecting the position and depth, respectively, with different forms of dual antenna reception mode, the operation not only makes the process easier, but also further improve the detection accuracy; ★ planar detection while retaining the traditional peak method and the zero value method, the using signal comparison approach to value and sound way to indicate the relative position of the receiver and the pipeline, making the process line to distinguish more clearly reliable; ★ direct calculation method, in digital form display pipeline depth, while semi-polar value method, 80% method as sounding adjunct; ★ simple operation, small size, light weight, suitable for field work.
