    Complete functions

    • Electromagnetic induction principle, the transmitter probe emits electromagnetic waves, and the receiver receives electromagnetic waves. It has the advantages of not interfering with the fluid, long-distance detection, and adaptability to various flow ranges.
    • The transmitter probe has a self-check function. After turning it on, the probe can automatically detect whether it is operating normally, improving work efficiency.
    • Strong signal penetration, the maximum detection depth can penetrate the pipe blockage point under the 40cm thick cement wall/ floor, reducing the demolition area.

    Reliable quality

    • Large-capacity lithium battery, transmitter 2600mAh, receiver 1400mAh, working time can reach 10h/5h after a full charge and a double-head charging cable is used.
    • The signal line is durable, the probe line is made of polymer material, the surface is smooth, can be bent, and is not easy to break.
    • IP67 waterproof probe can accurately detect even in harsh environments with water, and 6 probes are standard for replacement.




    This pipe detector is suitable for a variety of scenarios. It can detect metal pipes such as iron pipes, cement pipes, steel pipes, copper tubes, and non-metal pipes such as PVC pipes and plastic pipes. The pipe detector machine has good applications for blockage problems in scenes buried in cement walls, ground, and land. In short, the pipe blockage detector is an indispensable device in pipeline maintenance. It not only improves work efficiency and reduces maintenance costs, but also provides important support for ensuring the stable operation of industrial production and urban water supply systems.

    Q1: How does a pipe detector work?
    A1: Pipe blockage detectors generally use the principle of radio transmission and reception. It sends a specific signal. When encountering a blockage, the propagation of the signal will change, and the specific location of the blockage is determined by the signal change captured by the receiver.

    Q2: What factors can affect pipe detectors?
    A2: During use, it is necessary to consider many factors such as pipeline material, structural characteristics, external environment, fluid state in the pipeline, as well as equipment performance, and operator skill level. Through reasonable use and scientific operation, interference can be minimized and the accuracy and efficiency of detection can be improved.

    Q3: How do I store a pipe detector when not in use?
    A3: When the pipe blockage detector is not used for a long time, it should be stored in a dry, cool, dust-free environment, preferably in an air-conditioned room. The storage location should be away from direct sunlight and high-temperature sources to prevent the device from overheating and damage. At the same time, the device should be powered on and tested regularly to keep it in good working condition.

    Tips: Features of water leak detector pipe blockage detector.

    The pipe blockage detector has many significant features, such as precise positioning, saving labor and materials, and a small damage range. In practical applications, large-area excavation in traditional methods is avoided, significantly reducing project costs and time consumption. In addition, modern water pipe detectors usually have waterproof and anti-vibration designs and are suitable for various complex working environments.

    • Precise Positioning and Reduction of Damage
      One of the major advantages of the PVC pipe detector is that it can accurately locate blockage points in the pipeline, and can also monitor the operating status of the pipeline system in real time, detect abnormal flow or blockage problems in a timely manner, and avoid production interruptions and energy waste caused by underground PVC pipe locator, problems and safety incidents, etc. Thus saving operating costs.
    • Versatility and Applicability
      The versatility of pipe finders is also one of the reasons for their popularity. For example, the pipe blockage detector can not only detect iron pipes and PVC pipes but can also penetrate 50cm thick walls to adapt to different environments and material requirements. Ease of operation is another major advantage of the water pipe detector. Users only need simple training to get started with the operation. Users can adjust the sensitivity and detection distance of the detector as needed to quickly determine the location of the blockage.
    • Durable and Low Power Consumption
      The design of the pipe locator focuses on durability and low power consumption. On this basis, the battery design of the pipeline blockage detector takes into account convenience.

    Cost-effective pipe detector
    I use this to check the pipe problems in the basement wall. The house has been in disrepair for a long time, and the cost of removing pipes on a large scale is too high. This detector perfectly solves this big problem of mine. It finds blockages within 2 inches and also finds the drain pipes that are damaged by the downspout. I personally think it is quite practical.
