PH Tool Phased Array PACS™ Block

The PH Tool Phased Array PACS™ Block is used for angle beam verification, probe angle exit point, calibration for wedge delay, sensitivity, DAC/TCG for thicknesses up to 2″.   The three radii (0.500, 1.000, 2.000″) allow for exit point verification, velocity, and sound path calculations. The PACS™ Block contains five holes at 3/64″ diameter drilled through the 1.000″ width, located at .100, .200, .400, .600, .800, 1.200, 1.400, 1.600, 1.800, and 1.900″ from the respective scanning surface. Generous hole spacing eliminated “ghost” images from adjacent holes.  Also includes an engraved scale from 30° to 70° associated with the .800″ hole for beam angle verification.  The dimensions are 18.0″ x 2.0″ x 1.0″

Available in imperial and metric.  Also available in aluminum, steel, stainless steel and special alloy.

Standard test blocks are non-representative tools, meaning that they are not manufactured from actual parts. Rather, they are a simplified design that contains manufactured discontinuities such as holes, angles, radii and more. Standard test blocks serve the purpose of standardizing and calibrating test equipment to ensure it is functioning properly.

All test blocks ship with a NIST-traceable certification report stating that the block meets applicable specifications.

Optional fitted, wooden storage case is also available.
