UD3-204

 

 

 

 

UD3-204 is a general purpose ultrasonic flaw detector and thickness-gauge. 
It has such features as acoustic contact control, built-in DGS, simplified sensitivity set. It allows to load custom DGS-graphs from PC, has an algorithm for evaluation of sound attenuation in test piece, also a special mode for curved surfaces.
