Product Introduction
The HS900L electromagnetic ultrasonic low-frequency guided wave detector is an electromagnetic guided wave detector that does not require polishing, coupling, has a long transmission distance (up to 300m), and has high detection efficiency.
Functional Features
Suitable for long-distance internal and external corrosion detection of specific steel cables, steel bars, threaded steel and other workpieces
Integrated design, lightweight, small size, easy to carry
Directed emission (forward, reverse, bidirectional), no coupling agent required
The number of channels is 2, which can independently receive, transmit or control the direction by adjusting the phase
Equipped with ultrasonic guided wave mode selection dispersion curve function
Equipped with various functions such as 64 order digital filtering, wavelet denoising, and digital averaging for echo signals
Equipped with automatic calibration function for guided wave velocity
Equipped with full data recording and real-time analysis functions
The cable connecting the instrument and probe adopts a shielded structure, which has stronger anti-interference ability
