To what temperature is the Intoximeter sample chamber heated?

• A. 40°C (+/- 1°C)
• B. 37°C (+/- 1°C)
• C. 25°C
• D. 50°C

Answer: (A)

The sample chamber is kept at a controlled, heated temperature to ensure the breath sample entering the analyzer remains consistent. Specifically, it’s heated to about 40°C with a tolerance of ±1°C. This slight elevation above typical breath temperature helps prevent condensation and reduces surface adsorption inside the chamber, leading to a stable, reproducible infrared signal and accurate alcohol measurement. If the chamber were cooler, moisture could condense and skew readings; if it were hotter, it could introduce unnecessary thermal effects on the sample. The set point of 40°C ±1°C is chosen to optimize accuracy and calibration stability.
