PCE-FD 20 is a portable ultrasonic thickness tester or ultrasonic thickness gauge with a large LCD screen that displays A-scan maps of ultrasonic signals as well as B-scan cross sections. Ideal for use in mechanical engineering, aerospace and metallurgical applications, this high-frequency ultrasound-based thickness meter uses a contact transducer (two different probes included; 45° and 90°) to measure material thickness and identify flaws and defects such as discontinuity in welds.

• Operating frequency range: 1 … 10 MHz
• Measured time interval range: 6 … 1000 microseconds (µs)
• Sound velocity: 1000 … 9999 m/s
