ASTM DISTANCE AREA AMPLITUDE BLOCK SET OF 10

Distance Area Amplitude Calibration Blocks Per ASTM E428 For measuring dead zone, sensitivity, distance, and area amplitude linearity, a basic set of ten flat-bottom hole blocks is employed. Metal Travel Distance: 3/64" - 3.0" (3-0300), 5/64" -.12" (5-0012), 5/64" -.25" (5-0050), 5/64" -.75" (5-0075), 5/64" - 1.5" (5-0150), 5/64" - 3.0" (5-0300), 5/64" - 6.0" (5-0600), and 8/64" - 6.0" are among the hole diameters and metal travel distances included in the (8-0600).
