Calibration Block No.1 (Inch Version) ALUMINUM 7075-T6 

Calibration Block No.1 are used to calibrate instruments for both angle beam and normal incident inspections. Some of their uses include setting metal-distance and sensitivity settings, determining the sound exit point and refracted angle of angle beam transducers, and evaluating depth resolution of normal beam inspection setups.

For calibrating ultrasonic flaw detection equipment in both laboratory and on-site conditions. Our version of this block includes a 4" radius, 0.12" and 2" holes, engraved reference mark scales, and two optional slots at the zero point which provide calibrating signals at intervals of 4" range. In accordance with EN 12223 and ISO 2400. 

This block is not to be confused with the older style "V1/5 (A2)" Block from BS 2704, which is similar but contains a 0.06" through-hole rather than a 0.12" hole. 

Geometry: 4" radius, 0.12" and 2" holes, engraved reference mark scales, and two optional slots at the zero point which provide calibrating signals at intervals of 4" range.

Dimensions: 12"(L) x 4"(W) x 1"(T).

Material: ALUMINUM 7075-T6
