Final Answer:
The system used to measure the thickness of sheet metal products is a Caliper gauge (A).
Step-by-step explanation:
A (A).Caliper gauge is a precise instrument designed for measuring the thickness of sheet metal and other materials. It consists of two arms, one of which is stationary, while the other can be adjusted.
By placing the caliper on either side of the sheet metal, the user can measure the distance between the arms, providing an accurate measurement of the material's thickness. This method ensures precision in determining the thickness of sheet metal products, critical for various manufacturing and engineering applications.
The accuracy of measurements is crucial in industries where sheet metal is used, such as construction, manufacturing, and engineering. Using a caliper gauge allows professionals to obtain precise thickness measurements, ensuring that the sheet metal meets the required specifications. The caliper gauge is preferred over other tools like rulers or thermometers for this purpose due to its ability to provide accurate and consistent measurements, contributing to the overall quality and reliability of the manufactured products.
