PH TOOL 5-Step Calibration Block (Inch) - 1018 Steel, with Fitted Case

Ensure unparalleled accuracy and reliability in your ultrasonic thickness measurements with this essential PH TOOL 5-Step Calibration Block. Precision-machined from durable 1018 Steel and supplied with a protective fitted case, this block is the go-to standard for calibrating and verifying the linearity of your ultrasonic thickness gauges in accordance with industry specifications.

Key Features & Benefits:

• Precise Thickness References: This inch-version 5-step block features five accurately machined steps with nominal thicknesses of:

  • 0.100" (100 mils)

  • 0.200" (200 mils)

  • 0.300" (300 mils)

  • 0.400" (400 mils)

  • 0.500" (500 mils) These precise steps allow for comprehensive calibration and verification across a practical range of thicknesses.

• ASTM E797 Compliant: Manufactured in strict accordance with ASTM E797 (Standard Practice for Measuring Thickness by Manual Ultrasonic Pulse-Echo Contact Method), ensuring that your calibrations meet recognized international standards.

• Optimal for Linearity Calibration: Crucial for confirming that your thickness gauge provides accurate readings across its entire measurement range, not just at a single point.

• Durable 1018 Steel Construction: Made from high-quality 1018 Carbon Steel, a common and acoustically stable material, ensuring long-term integrity and consistent acoustic properties for reliable calibration.

• Generous Step Faces: Each step features a 0.75" x 0.75" (approx. 19mm x 19mm) face, providing ample surface area for stable transducer placement and effective acoustic coupling.

• Includes Fitted Protective Case: Comes with a custom-fitted wooden or durable hard-plastic storage case. This protects the precision-machined surfaces of the block from damage, dust, and corrosion, preserving its accuracy and extending its lifespan, while also making it easy to transport.

• Traceability (Optional Certificate): While the block itself is manufactured to specifications, a Certificate of Accuracy (often optional from PH TOOL at additional cost) can provide full traceability to NIST and other national standards bodies, which is vital for many quality management systems.

• Essential for NDT Professionals: An indispensable tool for ultrasonic technicians, inspectors, and quality control personnel in industries such as manufacturing, aerospace, oil & gas, and general maintenance.

Ideal For:

• Calibrating ultrasonic thickness gauges.

• Verifying linearity of thickness measurements.

• Training and certification of UT technicians.

• Ensuring compliance with industry standards for accurate thickness data.
