Product Description
Overview
The CJ-10 Ultrasonic Pulse Velocity Tester is a professional-grade NDT instrument designed to assess the internal integrity and homogeneity of concrete. Using pulse wave transmission, it evaluates the presence of voids, cracks, and other structural defects in both in-situ and precast concrete. The device also supports strength estimation, concrete pile testing, and can interface with a rebound hammer via Bluetooth for comprehensive material analysis.
