1. Pipe closure detector with large range: The pipe clogging detector consists of two parts: a feeder machine and a receiver. The feeder is equipped with a 20/30/40 m ultralong signal line and a sensitive waterproof probe. It can detect precisely even in a water environment and detect pipelines with a maximum depth of no more than 40 cm. 2. precise detection: The tube finder is equipped with a precision signal receiver that uses electromagnetic induction for detection, features a sensitivity adjustment knob for continuous adjustment, and has an LED display. The closer to the blockage, the more lights illuminate. It also produces different loud buzzing sounds depending on the signal strength to locate the blockage. 3. Large capacity battery: The stringing machine and receiver are equipped with capacity batteries (2600 mAh/1400 mAh). They can operate continuously for 10 hours/5 hours and come with a dualhead charger for simultaneous charging of both devices. An automatic shutoff function turns them off after 1 hour/0.5 hours of inactivity. 4. Userfriendly design: The stringing machine features a nonslip handle and a wire tube spool for comfortable and quick line retraction. It also includes wired headphones for easy use in noisy environments. Additionally, the probe has a poweron selftest function, significantly improving work efficiency.
