STEP Calibration Block: Ultrasonic Thickness Measurement

Reliable reference for ultrasonic thickness verification.

The ultrasonic thickness calibration test blocks are designed for routine verification and confidence checks of ultrasonic thickness gauges. It provides a stable, repeatable reference for confirming instrument performance before use, during inspections, or as part of quality control procedures.

Manufactured from homogeneous material and finished to tight dimensional tolerances, these blocks support consistent and repeatable ultrasonic measurements.

Typical Applications

• Daily or pre-use instrument checks

• Thickness gauge performance verification

• Training and competency assessments

• Quality assurance and audit preparation

• Workshop and field reference measurements

Features

• Precision-machined reference thickness

• Homogeneous material for stable ultrasonic response

• Smooth measurement surface for reliable coupling

• Durable construction suitable for field or lab use

• Clear identification of the nominal thickness value

• QR Code for digital calibration certificate

Compatibility

Suitable for use with:

• Ultrasonic thickness gauges

• Single-element contact probes

• Common ultrasonic couplants

What This Block Is (and Isn’t)

This block is:

• A reference artefact for instrument verification

• A practical check tool for inspectors and technicians

This block is not:

• A replacement for ISO 17025 instrument calibration

• A probe-specific or application-specific setup standard

Care & Handling

• Keep surfaces clean and free from corrosion

• Store in a protective case when not in use

• Avoid mechanical damage that may affect the thickness accuracy

Important Notes

• Nominal thickness values are engraved or supplied with documentation

• This block is intended for verification, not acceptance testing

• Users are responsible for ensuring suitability for their procedures
