Olympus, a world leader in nondestructive testing technologies, is pleased to introduce the EPOCH 650 digital ultrasonic flaw detector that combines industry-leading conventional ultrasonic flaw detection capabilities with the efficiency of a highly portable, intuitive instrument.
The EPOCH 650 is a continuation of the popular EPOCH 600 flaw detector (launched in 2010) and provides excellent performance and usability for a wide variety of applications. Its intuitive user interface is appropriate for both novice and experienced users, and its portability and rugged ergonomic design allow convenient operation in nearly any inspection environment. Available in two hardware configurations, the compact EPOCH 650 offers the choice to adjust parameters with a knob or with a navigation area on the keypad. The large, color transflective VGA display is complemented by a full screen A-scan mode, providing a vivid A-scan representation in both low light and bright sunlight conditions. The EPOCH 650 patented digital High Dynamic Range receiver meets the requirements of EN12668-1:2010, and the instrument allows a full range of standard and optional flaw detection features. Key standard flaw detection features include 400V PerfectSquare tunable square wave pulser, up to 30 digital filters for enhanced signal-to-noise ratio, flexible reporting capabilities direct to removable memory, dynamic DAC/TCG, onboard DGS/AVG, AWS D.1.1 / D1.5 weld rating software, and Echo-to-Echo measurements with gate tracking. Optional application-specific software programs include an Interface tracking gate, Backwall Echo Attenuator (BEA), API 5UE, and Waveform Averaging.
Economical Size, Quality Performance
The large, full VGA transflective display combined with our patented digital high dynamic range receiver provides a stable, striking A-scan representation in any lighting condition. The EPOCH 650 is designed to meet the requirements of EN12668â??1 and allows a full range of standard and optional flaw detection features. Multiple onboard reporting tools and a comprehensive data filing system enable you to easily collect and report high quality inspection data. The rugged, ergonomic design allows use in nearly any inspection environment, while the flexible PerfectSquare pulser and highest number of digital filters in its class can tackle nearly any application.
The EPOCH 650 Digital Ultrasonic Flaw Detector combines Olympus industry leading conventional flaw detection capabilities with the efficiency of a highly portable, intuitive instrument. The EPOCH 650 flaw detector blend of efficient menus and direct access keys allows you to take advantage of the highest quality flaw detection platform with exceptional ease of use.
