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 ISO 22232-1 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’s 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.
Designed for All Inspection Environments
The EPOCH 650 is designed for use in nearly any inspection environment, from bench top testing in a laboratory to extreme outdoor and hazardous conditions. Designed for IP rating in either knob (IP66) or navigation pad (IP67) configurations, and tested to very high environmental and reliability standards, the EPOCH 650 allows users in any inspection environment to feel confident in both the performance and durability of the instrument.
Simple and Comfortable Operation
The EPOCH 650 design is focused on providing a very high level of flaw detection with the simplicity of a basic instrument. The EPOCH 650 is designed to be ergonomic, intuitive, and practical for both experienced and novice ultrasonic inspectors.
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!
Options for Comfortable Navigation
In order to accommodate different user needs and preferences, the EPOCH 650 is available in two hardware configurations:
The adjustment knob on the EPOCH 650 is used along with the CHECK and ESC keys to adjust parameter values in either coarse or fine increments. You have the ability to lock the knob to prevent accidental parameter value changes during an inspection. This configuration provides smooth value slewing for customers who prefer adjusting parameters using a knob. The knob configuration is designed to meet the requirements of IP66.
The EPOCH 650 navigation pad is a hallmark feature of the EPOCH flaw detectors. The up and down arrows on the navigation pad are used for coarse parameter adjustment, and the left and right arrows for fine adjustment. The navigation pad also contains additional functions and frequently used parameters such as gain, save, and the CHECK and ESC keys. The navigation pad configuration is designed to meet the requirements of IP67.
