A vernier caliper is a precision measuring instrument that uses a sliding vernier scale alongside a main graduated scale to read dimensions with accuracy beyond the main scale's least division. It comprises a main beam with fixed jaws and a sliding jaw assembly with a vernier scale, plus a depth rod, enabling measurement of external dimensions, internal dimensions, and depth. It persists as a manufactured physical instrument. [formal: caliper vernier | substrate: matter | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A vernier caliper is a human-made precision measuring instrument that uses a sliding vernier scale alongside a main scale to read dimensions with greater accuracy than the main scale alone. It measures internal, external, and depth dimensions through jaw-based contact with the object.

Sense: gauge as measuring device (not as verification procedure). A vernier caliper is a specific type of precision measuring device that compares unknown dimensions against a known scale. Removal test (for DEPENDS_ON): remove the concept of 'gauge' and vernier-caliper loses its category — it is a kind of gauge. This is INSTANCE_OF: specific→nearest general kind.
