CL200 pipe leak detectors are a professional instrument that water supply companies,heating companies, municipal construction companies and property companies inspect whether underground pipes leak water.They are mainly used to find and determine the location of leakage points of water supply pipeline,and they can also be used to detect the leakage of other pressure piping systems.When the fluid in pipeline erupts through leakage source due to the pressure,the noise produced by the impact on the internal wall will spread along the pipeline or along the buried layer medium to the ground,and the instrument determines the leakage source through an industrial-grade amplification of leakage noise.
