ASTM E2491 Phased Array Assessment Block (Metric Version) ALUMINUM 7075-T6

ASTM E2491 Phased Array Assessment Block (Metric Version) is a general purpose Phased Array calibration block used for beam characterization and evaluation of system performance characteristics. Use it as a baseline block to determine long-term instrument performance changes, generate DAC curves and evaluate linear/angular resolution, focusing ability and beam steering capabilities. With a variety of targets, this small, lightweight block is also perfect for customer demonstrations of phased array ultrasonic capabilities. This block is also referred to as a “Type B” block.
