Four-step metric reference blocks for setting up ultrasonic thickness gauges and checking readings across a practical range of wall thicknesses.
Key features
- Two metric step arrangements with carbon-steel and stainless-steel options.
- Known thickness steps for multi-point instrument checks.
- Select the material and thickness arrangement to suit the workpiece and probe.
Applications
- Thickness-gauge checks before corrosion surveys of tanks, piping and plate.
- Maintenance inspection in mining, process plant and fabrication.
- Material-velocity setup and routine gauge verification.
