Products Description
The HS900L is an electromagnetic ultrasonic detector specialized in low-frequency guided wave detection. Utilizing electromagnetic technology, it can detect guided waves without requiring grinding or coupling. It offers a long transmission range of up to 300 meters and ensures high detection efficiency.
Performance Feature
●Ideal for non-destructive inspection of internal and external corrosion over long distances in workpieces such as steel cables, bars, and threaded steel components.
●Its integrated design offers a lightweight, compact structure for easy portability.
●Capable of transmitting signals directionally (both forward and reverse) or bidirectionally without the need for a coupling agent.
●Features a dual-channel configuration, enabling independent signal transmission and reception through two channels, or directional control through phase adjustments.
●Supports ultrasonic guided wave mode selection with a dispersion curve.
●Includes advanced features like 64-order digital filtering of echo signals, wavelet-based noise reduction, and digital averaging for enhanced performance.
●Equipped with an automatic guided wave velocity calibration feature.
●Capable of complete data recording and storage, along with real-time analysis capabilities.
●The connection cable between the instrument and probe is shielded for enhanced anti-interference performance.
●Provides test result output and defect statistics reports.
