Ultrasonic Flaw Detector (KFD 90)

Digital Ultrasonic Flaw Detector KFD 90 High Performance

User preferred features
* Simple operation with fast rotary knob adjustments; Gain is always directly accessible with the left-hand key and lockable.
* Auto CAL makes calibration fast & easy
* 7 selectable material velocities at the user's fingertips.
* 2 independent gates monitor amplitude and sound path distance for both flaw detection and thickness measurement applications.
* 400 KHz to 25 MHz capability with 3 selectable frequency ranges to match probe for optimum performance.
* RF display mode enhances signal evaluation and bond inspection of dissimilar materials.
* 4 selectable damping settings (50, 75, 150, 500 ohms) for optimum probe performance.
* 1mm to 10m range (in steel) covers thin to lengthy acoustically clean materials.
* dB REF key evaluates subsequent echoes gain value and amplitude against the highest echo in Gate A (reference echo) when activated.
