Olympus NDT, Waltham, MA, has introduced the EPOCH 600 digital ultrasonic flaw detector, a portable instrument that enables several methods of storing, archiving, and reporting inspection and calibration data. It features onboard memory up to 50,000 individual waveform files, plus an additional 2 GBs of removable memory. Users can adjust parameters with a knob or with a navigation area on the keypad. Key standard flaw detection features include 400V PerfectSquare™ tunable square-wave pulser, digital filtering for enhanced signal-to-noise ratio, single-shot measurements at up to 2,000 Hz PRF, and Echo-to-Echo measurements with gate tracking. A color transflective VGA display and digital high-dynamic-range receiver provide A-scan representation in both low light and bright sunlight. The navigation pad configuration with sealed case meets IP67 requirements for wet or dusty conditions; the knob configuration meets IP66 requirements. It features a battery life of 12 to 13 hours, enabling use in remote and limited-access inspection locations.
