Products Description
The HS900L is an electromagnetic ultrasonic low-frequency guided wave detector that utilizes electromagnetic technology to detect guided waves. It eliminates the need for grinding or coupling, offering a long transmission range of up to 300 meters and ensuring high detection efficiency.
Performance Feature
●Ideal for non-destructive testing of internal and external corrosion over long distances in targeted components such as steel cables, bars, and threaded steel parts.
●Its all-in-one design ensures a lightweight, compact structure that makes it easy to carry.
●It supports directional signal transmission (both forward and reverse) as well as bidirectional transmission, without the need for a coupling agent.
●With its dual-channel configuration, the system allows for separate transmission and reception through two channels, or directional control by adjusting phase settings.
●Offers ultrasonic guided wave mode selection with a dispersion curve function.
●Features advanced signal processing, including 64th-order digital echo filtering, wavelet-based noise reduction, and digital averaging.
●It is equipped with an automatic calibration function for guided wave velocity.
●It offers full data recording and storage capabilities, along with real-time analysis features.
●The connecting cable between the instrument and the probe features a shielded design, providing enhanced anti-interference capability.
●Provides output for test results and defect statistics reports.
