Olympus / Panametrics-NDT EPOCH 4 Ultrasonic Flaw Detector
The Panametrics-NDT EPOCH 4 is an advanced digital
ultrasonic flaw detector that combines powerful, fully featured
measurement capabilities, a comprehensive internal datalogger, and a wide
range of software options to solve many demanding inspection problems.
Signal processing features include a 25 MHz bandwidth
to permit testing of thinner materials, a selectable square wave pulser to
optimize penetration on thick or attenuating materials, and narrowband
filters to improve signal-to-noise ratio in high gain applications. The
EPOCH 4 incorporates rugged packaging and a conveniently organized
direct-access keypad, and offers the choice of high-resolution Liquid
Crystal or Electroluminescent displays.
