PCE Instruments FD 20 Portable Ultrasonic Flaw Detector 1 to 10 MHz

Model # FD 20

PCE-FD 20 is a portable ultrasonic defectoscope 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 defectoscope uses a contact transducer (two different probes included; 45° and 90°) to measure the material thickness and identify flaws and defects such as discontinuity in welds.
