Class Instrumentation Ltd Ultrasonic Sound VDownload PDFelocity Table

 

A sound velocity table is a list of the speed of sound in various materials.  This information is necessary to have when using our Touchstone 1 ultrasonic thickness gauge, as the speed the ultrasound will move through the material in question needs to be programmed into the gauge to obtain an accurate thickness reading.

All velocities in this sound velocity table are approximations:
