Features
● Integrated dual-function testing: Realizes one-device measurement of both concrete crack width and depth, eliminating the need for multiple instruments
● High-precision probe matching: Equipped with standard and high-grade color amplification probes for crack width, plus ultrasonic probes for depth, adapting to different testing requirements
● Intelligent recognition & calculation: Automatically identifies crack images, calculates width and depth values in real time, and supports manual/intelligent/scale testing methods for width
● Multiple depth testing modes: Offers non cross-crack, cross-crack and simplified test modes for crack depth, flexible for various on-site concrete structure conditions
● Massive data storage: 4GB SD card supports storing over 200,000 test documents, preserving crack images and depth data for long-term traceability
● Professional post-processing software: Enables data transmission, image viewing, file editing, and report printing, supporting both single and multi-image display for crack analysis
● User-friendly operation: Adopts touch screen and keyboard dual control, with WinCE operating system for easy operation; auto-generates test numbers for efficient on-site work
● Rugged on-site design: Low power consumption with long battery life, wide working temperature and humidity range, suitable for harsh construction site environments
● Precise probe positioning: Ultrasonic transducer holder with adjustable and accurate testing point spacing, no on-site marking required to improve testing efficiency
Applications
Concrete crack width detectors are widely used for testing concrete structures such as bridges, roads, tunnels, high-rise buildings, dams, airports, and industrial plants.
