The Thickness Gauge Step Wedge blocks are made from 1080 Low Carbon Steel and have 4 different step heights.

These are commonly used to verify and adjust the calibration of you ultrasonic thickness gauge and transducer before or during NDT testing.

The step wedge block allows users to select a 'step' thickness closest to the material part(s) under inspection or for 2-point calibration to improve testing accuracy.

The step wedge can also be NATA verified or "calibrated" and we can offer this as an add-on service. Please contact us for pricing.
