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:
Knob
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.
Navigation Pad
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.

Software
Optimized Access to Powerful Features
The EPOCH 650 provides excellent quality ultrasonic performance. Based on the same digital architecture as the EPOCH 600 and EPOCH 1000 Series, the EPOCH 650 provides flexible, powerful pulsing and receiving features to accommodate the needs of most flaw detection inspections.
Pulser/Receiver
The EPOCH 650 comes standard with powerful flaw detection capabilities, such as:
- PerfectSquareTM tunable square wave pulser
- Digital high dynamic range receiver
- Thirty (30) 100% digital filter sets
- Auto or manually adjustable PRF from 10 Hz to 2000 Hz
- Pulser voltage from 100 V to 400 V
- Amplitude resolution to ± 0.25%
- Five customizable digital measurements
Standard Software Features
Dynamic DAC/TCG: Calculates signal amplitude as a percentage or decibel level compared to a DAC curve or a reference echo amplitude fixed at a time-varied gain. DAC versions include Standard, ASME 3, JIS, and Custom. Also includes several key features: dynamically adjustable DAC curves, switchable DAC and TCG views, custom DAC warning curves, and 20-80% DAC views.
DGS/AVG: This flaw sizing technique allows echo signals to be evaluated with a DGS/AVG diagram associated to
a particular type of probe and material. The DGS/AVG diagram illustrates the relationships between echo height, flaw size, and distance from the transducer.
AWS D1.1 and D1.5: Provides a dynamic reflector indication rating for various AWS weld inspection applications. This allows more efficient inspections by eliminating manual calculations.
