A4 Calibration Test Block (20mm METRIC VERSION) 1018 Steel

The miniature angle-beam is a calibration block that was designed for the US Air Force for use in the field for instrument calibration. The block is much smaller and lighter than the IIW block but performs many of the same functions. The miniature angle-beam block can be used to check the beam angle and exit point of the transducer. The block can also be used to make metal-distance and sensitivity calibrations for both angle and normal-beam inspection setups.

20mm thick small calibration block for on-site checking of miniature shear wave probe index, time base, beam angle and gain. Includes a 25mm and 50 mm radius, 5mm hole, engraved reference mark scales from 35° to 75° degrees. In accordance with British Standard BS 2704 block A4, Fig. 4, and AS 2083.
