🔍 Key Concepts

• How an oxygen indicator cell works (it consumes oxygen chemically or electrochemically from a small fixed sample) • Difference between an instrument’s response time and long‑term drift or temperature effects • What happens to the oxygen content inside the sample chamber after the sample is sealed and measured

💭 Think About

• Ask yourself: if the instrument uses up the oxygen inside a small fixed volume, will the reading stay where it is, or change over time? In which direction? • Think about whether the instrument should give a stable reading long enough for you to read it, or whether you’d expect it to keep moving as conditions change. • Consider which option describes a realistic, practical behavior for safe cargo tank testing in terms of getting a clear, trustworthy reading.

✅ Before You Answer

• Verify which choices describe the needle staying steady long enough to be read accurately. • Check which options involve the oxygen in the sample being consumed inside the instrument, and what that would do to the reading over time. • Eliminate any option where the reading is clearly unreliable or misleading for tank safety testing (e.g., obviously false due to temperature drift).
