每个应用中都应使用校准和/或参考试块。我们备有用于普通材料的角度声束校准和厚度校准的标准试块。
Calibration and/or Reference Blocks should be used in every application. Standard blocks are available for angle beam calibrations and thickness calibrations of common materials.
Blocks manufactured from 1018 steel, 304 stainless steel, or 7075-T6 aluminum are commonly in stock (other materials require special quotes for price and delivery)
