Demeq QSV Series Sound Velocity and Nodularity Gauges are used to identify material types based on their sound velocity. In the foundry industry, a direct relationship can be established between sound velocity and cast structure, making these instruments especially useful for distinguishing between grey cast iron and nodular (ductile) cast iron.
By analyzing variations in sound velocity, the QSV Series provides a reliable, non‑destructive method for material characterization and nodularity assessment in casting quality control applications.
