Measurement working principle indoor pipeline leak detection monitor collects leaking sound signal through collected signal, Its sensor will undergo processing by host machine and displayed on the host machine screen presented as of visual spectrum and signal bars. Simultaneously time, The sound will also be output to its earphone through the host machine. Water leakage point is present out easily through the integration of listening to the abnormal sound and observing the abnormal signal bars . High precision detector effectively solving the problem of water leakage in the household pipeline electronic earphone leak detector water host machine, 1xsquare sensor 1xtriangle sensor, Pipe detection equipment kit, 1 x earphone. The closer the detector serves as the greater, The leak the jerk indicating that, Will sound the columnar will be higher and the user will gain the capability to operate to sense the leak.
