Underground pipeline locator

Product introduction:

The transmitter's built-in ohmmeter automatically measures loop resistance and continuous automatic output impedance matching to ensure optimal output matching. Depending on the needs of the actual application, the GH-6600B underground pipeline locator can be equipped with coupling clamps for the search of the path of the live cable without having to power off. The GH-6600B underground pipeline locator uses the 50Hz detection function of the receiver, and can also track the 50Hz power frequency signal sent by the running cable. It is truly multi-purpose and has the best performance-price ratio.
Product nickname:
GH-6600B underground pipeline locator, underground pipeline detector
Features:
(1) Pipeline positioning: Select the peak method and use parallel antenna positioning to quickly track the target pipeline. When the pipeline is above the pipeline, the signal is the largest and both sides are reduced. The trough method is selected, and the vertical antenna is used for positioning. When there is no adjacent pipeline and interference source, the positioning is more accurate and reliable. When the receiver is above the pipeline, the signal is the smallest and the signals on both sides are large.
(2) Depth measurement: directly measure depth in direct connection mode. Under normal circumstances, the error is about 10%. Place the receiver directly above the pipeline, adjust the gain so that the bar display value is around 600 ~ 800, press the depth button, the receiver shows the depth of the pipeline under test.
(3) Current measurement: Since the current value in the pipeline under test does not change with depth, the current measurement of the target pipeline helps determine the target pipeline and identify the T-tube branch. In general, it is only suitable for direct connection mode.
