Which instrument is a single-axis digital gauge used for quick dimensional checks?

• A. Micrometers
• B. Vernier calipers
• C. Digital test gauge
• D. Coordinate measuring machine

Answer: (C)

This is about recognizing a tool built for fast, one-dimensional measurements with a digital readout. A digital test gauge fits that description: it measures along a single axis and shows the result on a digital display, making quick dimensional checks on parts easy and immediate. It’s ideal for go/no-go checks or simple thickness/gap measurements on the shop floor, where speed and simplicity matter. Other tools are used for different needs. Micrometers and vernier calipers provide precise measurements but require reading scales and can be slower for quick checks, even in digital form. A coordinate measuring machine handles complex geometries across multiple axes, not just a single dimension.
