1Collect Sound Independently: The pickup recorder can collect sound independently. After plugging in the 929 device connector, it will automatically turn off the independent acquisition function and enter the connector acquisition state. 2Advanced Technology: The water pipe leak detector adopts new components and the most advanced technology in Japan, which increases the penetration force several times and greatly improves the sound quality. 3Sound Adjustment and Dual Detectors: The volume of the sound can be adjusted and switched according to the situation on site. Dual detector design, including probe and stylus. 4Wide Range of Applications: The underground water pipe leakage detector has strong practicability and is suitable for leak detection of various construction pipelines. 5Strong Penetrability: The underground water pipe leak detector has strong penetrability, whether it is water pipe, cement pipe or steel pipe, it can play a very good effect.
