Hardware Highlights• Built like a Krautkramer

– Weighs less than 4 kgs. (8 lbs.)– Shock proof, dust proof, water

resistant

• Unconventionally conventional– Becomes a code-compliant

conventional flaw detector with a single button click

• I am friendly, very friendly– USN60 layout with simple,

intuitive menus– Large (6.5” diagonal ) VGA

display screen– Secure transducer connects– SD card for easy data I/O

Single click and it is a code-compliant conventional UT flaw detector

Simple & user friendly

Measurement Tools OverviewGain Modification: Real Time and Playback

Display Result Correspondsto this Beam Angle

Reading boxes display user-defined parameters for the selected beam (selected beam angle is shown in small print

• Fast and accurate measurement

– Two sets of X-Y cursors for defect sizing and location

– Multiple gates– Angle and volume

correction– Auto detection of

optimum angle within defined gates

• Real time and in playback– Recalling data in freeze

mode– Level III can verify sizing

Value 1: Improved POD

Flaws are often optimized at angles different than the ones operators typically search at.

Phased Array also lowers the probability of missing flaws due to operator error.

“What is the value of 30% improvement in POD to your business?”
