What is the typical measurement range for a numeric thickness readout UT instrument?

• A. .010" to 10"
• B. .040" to 20"
• C. .100" to 25"
• D. .050" to 15"

Answer: (B)

The typical measurement range for a numeric thickness readout ultrasonic testing (UT) instrument is generally aligned with the capabilities and applications of such instruments in the field of inspection. The chosen range of .040" to 20" reflects the standard operating parameters for ultrasonic thickness gauges, allowing for effective measurement of various materials, particularly in inspecting piping components. This range covers relatively thin materials, such as certain piping used in chemical and oil industries, while also extending to thicker components that might be found in structural applications. Ultrasonic testing is favored for its ability to measure thickness accurately without damaging the materials being inspected, making it suitable for assessing the integrity and potential degradation of piping systems. The options that suggest measurement ranges outside of .040" to 20" fail to represent the typical capabilities of industry-standard UT instruments or may exceed practical limits for most common applications in piping system inspection. Therefore, .040" to 20" is considered a well-established and relevant range for effective thickness measurement in piping inspections.
