Ultrasonic Flaw Detector KFD 90

Digital Ultrasonic Flaw Detector KFD 90 High Performance

The KFD 90 combines the powerful advantages of digital design with the detailed dynamic echo information that was previously only possible with an analog display. Unique signal processing displays additional A-scan information as ÿ¯intensity variationsÿ?along the waveform to bring back the ÿ¯analog look & performanceÿ?that has been missing from digital instruments. The high resolution (640x480 pixels) color LCD display, 60 Hz update rate, and ÿ¯single shotÿ?measurement technique produce a fast, smooth response for immersion and critical weld testing.
The quality, durability, dependability and ease of use that you have come to expect of K&M`s popular KFD series of instruments remains. From rugged field inspections to high resolution thin measurements, long acoustically clean materials, and immersion systems work, the KFD 90 extends the range of applications that a portable instrument can perform.
