USC 20 is a portable or benchtop ultrasonic defectoscope or ultrasonic thickness gauge with a 5.7" TFT color LCD screen. This ultrasound-based defectoscope uses one or two contact transducers (four different probes included; 90 °, 70 °, 60 °, 45 °) to measure material or wall thickness, detect flaws or defects in welds, and monitor the effects of corrosion on pipes and tanks.

PCE-USC 20 is an ultrasonic defectoscope used for non-destructive testing (NDT) and inspection in a wide variety of applications in industries such as chemical, oil and gas, metallurgical, manufacturing, quality control,
