Calibration Blocks
Calibration/Reference/Standard blocks are available for Compression, Angle beam and Thickness calibrations of common materials. Blocks can be manufactured from steel, stainless steel, or aluminium commonly, although other materials may be used. Please Note these may require special quotes for price and delivery, feel free to contact us for more information regarding materials not listed, blocks not listed, or custom blocks. All blocks are checked dimensionally using measuring equipment IAW - EN, ASTM, ANSI, API Specs(Custom Blocks/Alternative specs catered for.) The most commonly required calibration blocks are listed below.
