Import Crack Depth And Width Tester — Buy in wholesale FOB from Supplier in China

The SYF71 Crack depth and width tester is a handheld instrument designed to measure both the depth and width of cracks in concrete, bridges, tunnels, walls and metal surfaces. It complies with China Housing Security accreditation standard GJ125-99 and the CECS 21:2000 ultrasonic inspection specification. The device features a 5‑inch colour LCD with a 640 × 480 pixel display and a dedicated scale for rapid on‑site readings. Its measurement range extends to a maximum depth of 650 mm with a stated error not exceeding 10 percent, and a width range of 0 to 8 mm with a resolution of 0.01 mm. The instrument can store up to 6 000 test records and up to 100 000 associated images. It operates on a rechargeable lithium‑ion battery that lasts for eight hours continuously, and it functions between - 10 °C and +50 °C. The host dimensions are 190 × 183 × 84 mm, making it portable for field work. Data can be transferred to a computer via USB without the need for removable media.

The tester incorporates an integrated ultrasonic sensor that interprets echo signals to calculate crack dimensions automatically, reducing operator bias. Typical industry devices in this class use similar ultrasonic transducers and provide depth accuracy within ±10 percent, which aligns with the SYF71 performance. The dedicated scale and real‑time visual ruler help operators define crack boundaries precisely, a standard practice in structural health monitoring. The built‑in Windows‑based analysis software enables export of results to Word or Excel, facilitating reporting that complies with most engineering specifications.

This instrument is used by bridge maintenance teams, tunnel inspection crews, civil engineering consultants and concrete pavement contractors who require documented crack measurements for safety assessments. The portable design and eight‑hour battery life support daily field surveys without frequent recharging. Buyers should confirm the supplied warranty, available calibration services and shipping terms directly with the supplier before placing an order.
