Kfd 90 portable ultrasonic tester *special ebay price*
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 intensity variations along the waveform to bring back the analog look & performance that has been missing from digital instruments. The high resolution (640x480 pixels) color LCD display, 60 Hz update rate, and single shot 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 from Martrow products extends to the popular KFD series of instruments. 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.
Square wave pulser for tough-to-penetrate materials
Square Wave Pulser selectable and tunable for optimum probe matching to satisfy a wide range of tough-to-penetrate applications.
Now, either spike or square wave pulser is user selectable from the front panel.
Spike pulsers are still preferred for everyday use.
For low frequencies, square wave pulsers allow optimum probe matching by adjusting pulse width and voltage.
Difficult to penetrate metallic applications and especially non-metals inspection like composite materials are optimized.
Pulse width is tunable up to 1000 ns in 10 ns steps for optimum probe matching and versatility in meeting a wide range of application.
Pulser voltage is adjustable from 50 to 500V in 10V steps.
KFD 90 durability, 6 hours of battery use, fast rotary knob operation, outstanding ultrasonic performance, and now square wave pulser and color leg combine to form a powerful portable ultrasonic inspection tool with new Lithium lon battery.
40 dB dynamic multiple curve DAC/TCG Option corrects for distance/amplitude variations from material loss and beam spread with ability to edit or insert recorded echoes individually. Up to ten DAC curves can be drawn on the screen at one time to show +/- dB curves in addition to the originally recorded DAC curve. Up to 16 data points can be recorded with a maximum curve slope of 12 dB per microsecond. Meets or exceed industry requirements for TCG.
Multiple curve DAC shows recorded DAC curve with 10 additional curves based upon db Offset feature for added flaw sizing assistance. TCG Attenuation and Transfer Correction features make it very versatile for use on other materials and surface conditions.
DGS (Distance Gain Size) Option displays a curve for a particular equivalent reflector size as a function of the distance from the probe to the reflector. The ERS (Equivalent reflector size) function automatically calculates the corresponding equivalent reflector diameter in mm or inches for any echo in the measurement gate.
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.
Store & preview a minimum of 512 user-names data sets with A-Scans for quick recall and instrument setup.
Alphanumeric Thickness Data logger for flexible, convenient storage of thickness readings in Linear, Grid, or Custom-Linear file structures with user-input filenames, location I.D. s, notes, header fields.
Hi-resolution (640 x 480 pixels) Color LCD Display with unique signal processing produces Analog Look and Performance echo dynamics.
Select from four vibrant display color schemes to match lighting conditions and personal preference.
Choose from eight A-scan colors to relieve boredom & eye fatigue.
Adjust brightness for easy viewing under all lighting conditions.
Gates and gate functions are color coded for easy identification and fast adjustment.
Tools for easy weld inspection
A-Scan dynamically changes the color for each leg of the live A-Scan.
Trigonometric flaw location function with curvature correction automatically calculates depth, surface distance, and sound path to flaw along with the leg of the inspection when using angle beam probes, All TOF measurements can be displayed in mm, inches.
Real time (single shot) TTL outputs handle a wide range of systems applications.
Choose from Four Freeze Modes: ALL, Peak Std, Compare or Envelope for optimum waveform evaluation and comparison.
Three Variable Persistence Modes are selectable in Freeze Envelope to visually assist flaw detection & evaluation for scanning and moving part inspections.
Compare frozen reference waveforms to live A-Scans in different colors to easily interpret test results.
RF display mode enhances signal evaluation and bond inspection of dissimilar materials
Corrosion-featured B-scan displays scanned thickness measurements of internally corroded pipe or tank walls as easy-to-read cross-sectional images.
FFull-featured B-scan features color-coded scan views, easy interprets cross sectional view of the inspected part, excellently displays corrosion mapping of boilers, pipes, and storage tanks. Visually identifies acquired flaws of the inspected part. Simultaneous viewing of an A-scan and B-scan is available.
Compare frozen reference waveforms to live A-Scans in different colors to easily interpret test results.
Peak-hold mode always keeps the signal that shows the maximum amplitude in the gate A.
