In regards to operating temperatures what does the Intox EC/IR II do?

• A. It records temperatures only at the start
• B. It ignores temperature
• C. It sets a fixed temperature
• D. The device constantly monitors operating temperatures throughout testing

Answer: (D)

Temperature control and monitoring are essential for accurate IR breath alcohol measurements. The Intox EC/IR II relies on infrared absorption to determine ethanol concentration, and that absorption can shift with temperature. To keep readings trustworthy, the device continuously monitors its operating temperatures—both the instrument’s internal temperatures and the breath sample’s temperature—throughout the testing process. This ongoing monitoring allows automatic temperature compensation and helps detect conditions that could skew results. If temperatures move out of range, the system can flag the issue or invalidate the test, rather than basing a result on a drifted or biased measurement. Recording temperatures only at the start isn’t sufficient because conditions can change during the test. Ignoring temperature would risk incorrect results, as would setting a fixed temperature that doesn’t reflect real-world variation. Continuous monitoring during testing ensures the measurement remains accurate and defensible.
