Intuitive User Interface
The EPOCH 650 user interface is based on the industry leading EPOCH 600 flaw detector. The EPOCH 650 combines a simple menu structure for instrument settings, calibration and software feature adjustment, with the EPOCH brand’s hallmark direct-access key approach
for critical inspection functions such as gain and gate adjustment, screen freeze, and file save. Supported in multiple languages, the EPOCH 650 user interface is intuitive for any level of operator.
Vibrant VGA Display with Full Screen Mode
The EPOCH 650 features a full VGA (640 x 480 pixels) resolution display. The horizontal design of the EPOCH 650 optimizes the A-scan size and readability on this high quality display. Built with transflective technology, this VGA display provides excellent clarity in indoor, low lighting conditions using its powerful backlight, as well as in direct sunlight by using the ambient light as a pseudo-backlight.
The full screen mode feature enhances this vibrant display to provide the largest A-scan in an EPOCH series flaw detector!
