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.
