The F71 Crack Comprehensive Detector is a portable field instrument designed for non-destructive evaluation of concrete and masonry structures. It measures crack depth up to 650 mm with a test error of ±10 mm and crack width from 0.01 mm to 0.8 mm with an accuracy of ±0.01 mm. The device stores up to 6,000 sets of depth data and can retain image and width data for 100,000 measurement points. Its LCD screen has a resolution of 160x128 pixels, providing clear readouts in varying light conditions.
The unit operates on a built-in rechargeable lithium battery, supporting continuous use for eight hours. It functions reliably within a temperature range of -10°C to +50°C, making it suitable for outdoor and industrial environments. The host dimensions are 190 mm by 183 mm by 84 mm, designed for single-handed operation. These specifications align with standard requirements for portable ultrasonic crack detectors used in civil engineering and infrastructure inspection.
This device is primarily purchased by civil engineering contractors, bridge maintenance teams, and government infrastructure inspectors in China and Southeast Asia. Buyers typically require units with verified data storage capacity and precise width measurement for compliance with GB/T 50784 standards. Trade terms are typically FOB Qingdao, with minimum order quantities negotiated directly with the supplier. Packaging includes a hard-shell case, charger, and calibration certificate.
