To accurately measure the internal diameter of a test tube, the most suitable instrument is a **caliper**, specifically a **digital caliper or a vernier caliper**.

Calipers are designed to measure small dimensions with precision. They can provide accurate readings and are particularly useful for measuring the internal diameter in a cylindrical shape like a test tube. The jaws of the caliper can be positioned inside the test tube, allowing for direct measurement of its internal diameter.

Beyond just calipers, methods like gauges or micrometers might be used, but they are less practical for this specific application as they are more suited for flat surfaces or smaller cylindrical objects.

In summary, for measuring the internal diameter of a test tube, use a digital caliper or a vernier caliper for the best accuracy and convenience.
