Ultrasonic Calibration Blocks

Ultrasonic Calibration Blocks or NDT (Non-Destructive Testing) calibration blocks are used to ensure the accuracy and reliability of Ultrasonic Thickness Gauges and Ultrsonic Flaw Detectors.

Calibration blocks provide known reference standards to check and adjust the performance of NDT equipment, such as ultrasonic Thickness and Flaw Detectors. By using these blocks, technicians can verify that their equipment is functioning correctly and providing accurate readings.
