In the construction process, PVC pipes and metal wire pipes are often blocked due to various reasons, and the wire box cannot be found. The location of the blockage point is difficult to determine, and the excavation area is large, causing high labor intensity for workers and even damaging the structure, which consumes a lot of manpower and financial resources. This instrument adopts the principle of microwave emission and is affected by external inductive interference. It can be used in PVC pipes and any electrical wires with a length of more than 50 centimeters. A about 2 meter thick wall can clearly find the blockage point and and remind you through a buzzer. It has a fast search speed, simple operation, stable performance, low power consumption, long service life, and labor-saving for maintenance without dismantling the pipeline. : 1. WATERPROOF PROBES: The pipeline blockage detector is equipped with 4 waterproof probes, which can cope with various environments and has a long service life. 2. ACCURATE LOCATING: This kit is mainly used to accurately locate the location of pipeline blockages and remind you through a buzzer, stable and reliable. 3. ABS HOUSING: The blockage tester shell is made of excellent ABS material, which is impact resistant, scratch resistant, and does not deform. 4. DETECTABLE PIPES: The pipeline blockage scanner is suitable for detecting steel, iron, and PVC pipeline, to prevent large scale blockage of pipelines. 5. RECEIVER: The receiver has a built-in induction coil to receive the magnetic signal from the pipeline, and the coil generates an induced current to calculate the direction and position of the transmitter. There are two receiving modes: Far (note: about 2M) and Near (note: about 50 centimeter). Then adjust the sensitivity knob, peak mode (maximum) or null mode (minimum) to locate the transmitter.
