Calibration Blocks

Calibration blocks are precision-machined reference standards used to verify the performance of ultrasonic probes, ensure calibration stability, and validate instrument accuracy before industrial inspections. These blocks are manufactured with exact dimensions, known reflectors, angled notches, side-drilled holes, and reference steps that help technicians set sensitivity, velocity, delay, and gain parameters correctly.

From corrosion surveys and weld testing to flaw detection and material evaluation, calibration blocks allow inspectors to confirm that thickness gauges, flaw detectors, and transducers are operating within required tolerances. These standards are essential in pipelines, aerospace components, refinery vessels, fabrication workshops, power plants, and any application that demands reproducible NDT measurements and traceable quality assurance.
