The PH Tool ASTM E2491 Phased Array Assessment Block “Type B”
A general purpose Phased Array calibration block used for beam characterization and evaluation
of system performance characteristics.

PH Tool - Phased Array Calibration Standard (PACS™)
Phased Array Calibration Standard (PACS™) used for angle beam verification, probe angle exit point, calibration for wedge delay, sensitivity, DAC/TCG for thicknesses up to 2".

PH Tool - Phased Array Calibration Block No 2 - 3/4" Thick
This new Phased Array calibration block designed by PH Tool contains all of the required features on the ASME Sec V Art 4 Basic Calibration Block, yet spaces the holes out on a longer, narrower block.

PH Tool - Phased Array Calibration Block N0 2 - 1 1/2" Thick
This new Phased Array calibration block designed by PH Tool contains all of the required features on the ASME Sec V Art 4 Basic Calibration Block, yet spaces the holes out on a longer, narrower block.

PH Tool - Phased Array Cal Block No. 3 - ¾" Thick
This Phased Array Calibration Block designed by Paul Holloway of Holloway NDT & Engineering contains all of the required features of the ASME Sec V Art 4 Basic Calibration Block for non-piping applications, yet spaces the holes out on a longer, narrower block. The block contains two holes at 3/32" diameter drilled through the 1.500" width, located at 1/2T and 3/4T

PH Tool - Phased Array Mini PACS™ Block
Mini PACS™ Block is a smaller, portable version of the original PACS™ Block.  The block includes a total of four holes at 3/64" diameter drilled through the 1.000" width, located at .200, .400, .600, .700, .800, .900, 1.100, and 1.300" from the respective scanning surface.

PH Tool - Phased Array PACS™ Notch Block
The PACS™ Notch Block has been specially designed for use with Phased Array instruments used for sizing of OD and ID-connected cracks.  The block contains four EDM slots at depths of 20, 40, 60, and 80%.
