NM01X0000002

This DAKOTA ULTRASONICS Calibration Block, made from 4340 steel and featuring 4 precisely machined steps, is an essential tool for calibrating ultrasonic testing (UT) equipment, specifically thickness gauges and flaw detectors. The 4340 steel material is a high-strength alloy known for its consistent acoustic properties, making it ideal for calibration standards.

This block is designed with four distinct thickness steps, typically in increments of 0.250 inches, ranging from 0.250" to 1.000" (e.g., 0.250", 0.500", 0.750", and 1.000 inches). These known thicknesses provide reference points for accurately setting up and verifying the linearity and accuracy of ultrasonic instruments. By obtaining consistent readings on each step, technicians can ensure their equipment is providing reliable thickness measurements and flaw detection capabilities.

Key Features and Benefits:

• High-Quality Material: Manufactured from 4340 steel, ensuring consistent acoustic properties and durability.

• Four Precision Steps: Provides four distinct thickness references for comprehensive calibration checks. Common thicknesses are 0.250", 0.500", 0.750", and 1.000 inches, but other configurations may exist.

• Accurate Machining: The steps are machined to tight tolerances (typically ±1% of the nominal thickness, as per Dakota Ultrasonics standards), ensuring the reliability of the calibration standard.

• Essential for Calibration: Used to calibrate ultrasonic thickness gauges for accurate material thickness measurements and to set up flaw detectors for proper depth and sensitivity adjustments.

• Traceability: Often supplied with a calibration certificate traceable to national standards (e.g., NIST), providing assurance of the block's accuracy.

• Versatile Use: Suitable for calibrating a wide range of ultrasonic testing equipment used in various industries, including manufacturing, aerospace, oil and gas, and infrastructure.
