4 STEP BLOCK – 5-20MM STEP BLOCK CARBON STEEL

The 4 Step Block is a calibration standard used primarily in ultrasonic testing for depth measurement and inspection accuracy. The block consists of four stepped surfaces of different known thicknesses, allowing operators to verify the performance and sensitivity of ultrasonic equipment. By placing the block in contact with a test surface and performing the test, the operator can compare the measurement results against the known step sizes to ensure the accuracy of the equipment.

Four stepped surfaces of known thickness, used for calibration.Designed for use with ultrasonic thickness gauges and other ultrasonic testing equipment.Commonly made from metal or steel, ensuring durability and reliability during testing.Accurate calibration tool for verifying equipment settings and ensuring proper operation.Can also be used for procedure development and maintenance checks.
