Curtis — 5-Step Aluminum UT Calibration Block
Metric Aluminum Ultrasonic Thickness Calibration Block with 2.5–12.5 mm Steps & Wood Case SKU: CB05ALMOverview
The Curtis 5-Step Aluminum UT Calibration Block is a precision reference block designed for ultrasonic thickness gauge calibration, linearity checks, and measurement verification. Manufactured from aluminum, this block provides known metric thickness values that help technicians confirm instrument accuracy before and during ultrasonic inspection work.
This 5-step configuration includes thicknesses of 2.5 mm, 5.0 mm, 7.5 mm, 10.0 mm, and 12.5 mm, making it a practical calibration tool for routine material thickness measurement, equipment verification, and QA/QC inspection workflows. Its stepped design allows inspectors to verify gauge response across multiple reference points using one compact block.
Supplied with a wood case, the CB05ALM provides a protected and organized calibration solution for field, shop, and laboratory NDT applications where reliable ultrasonic thickness measurement setup is required.
