PCE-USC 20 is a portable or benchtop condition monitoring ultrasonic tester or ultrasonic thickness gauge with a 5.7″ TFT color LCD screen. This ultrasound-based thickness meter 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 a condition monitoring ultrasonic thickness gauge 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, metalworking, welding, machining, engineering, product research and development, construction, transportation and aerospace.
