HS900L electromagnetic ultrasonic low-frequency guided wave detector is an electromagnetic guided wave detector that does not require grinding, coupling, long transmission distance (up to 300m), and high detection efficiency.
Performance Feature
→ Suitable for long-distance internal and external corrosion detection of specific steel cables, steel bars, thread steel and other workpieces
→ Integrated design, light weight, small size, easy to carry
→ Directional transmit (forward, reverse, two-way), no coupling agent is required
→ The number of channels is 2 channels, which can be independently received and transmitted by two channels, or the direction can be controlled by adjusting the phase
With the function of ultrasonic guided wave mode selection dispersion curve
→ With multiple functions such as 64-order digital filtering of echo signals, wavelet noise reduction, digital averaging, etc.
→ With guided wave sound velocity automatic calibration function
→ With the function of full data record and preservation, real-time analysis
→ The connecting cable between the instrument and the probe adopts a shielded structure, which has stronger anti-interference ability
→ Output test results and defect statistics report
