Products Description
The HS900L is an electromagnetic ultrasonic detector that specializes in low-frequency guided wave inspection. It uses electromagnetic technology to detect guided waves, eliminating the need for grinding or coupling. With a long transmission range of up to 300 meters, it ensures high detection efficiency.
Performance Feature
●Designed for long-distance, non-destructive inspection of internal and external corrosion in workpieces such as steel cables, steel bars, and threaded steel components.
●This device features an integrated, lightweight, and compact design, making it highly portable.
●Capable of directional signal transmission (both forward and reverse) or bidirectional transmission, with no need for a coupling agent.
●The dual-channel configuration allows independent transmission and reception on two separate channels, or directional control via phase adjustments.
●Supports ultrasonic guided wave mode selection with dispersion curve functionality.
●Includes advanced functions such as 64-order digital filtering of echo signals, wavelet-based noise reduction, and digital averaging.
●Automatically calibrates guided wave sound velocity.
●Allows full data recording and storage, along with real-time analysis.
●The connecting cable between the instrument and the probe uses a shielded structure for superior anti-interference capability.
●Generate reports for test results and defect statistics.
