Yeah, I used one last week to measure gas volumes during a reaction.

Root Explanation

Eudiometer → It is formed from "eu-" (from Greek "eu", meaning good or well) and "dromos" (from Greek "dromos", meaning running or course). The word refers to an instrument that measures the quality of air, indicating a good or well-running atmosphere.

Memory Tip

Think of 'eu-' meaning good and 'dromos' meaning running — this helps you remember that a eudiometer measures the quality of air, indicating how well it runs.
