How does environmental temperature affect the Intoxilyzer 9000 readings?

Environmental temperature plays a significant role in the accuracy of the Intoxilyzer 9000 readings. When the temperature is outside the device's optimal operating range, it can lead to inaccuracies in the results. For instance, extreme cold can slow down the chemical reactions occurring inside the device, potentially leading to lower readings. Conversely, high temperatures might accelerate these reactions, which could produce higher readings than what would be accurate.

Therefore, the assertion that extreme temperatures can influence the readings is correct, as the Intoxilyzer 9000 relies on specific temperature conditions to maintain its accuracy. It is calibrated to operate most effectively within a certain temperature range, and deviations from this range can affect the device's performance, thereby impacting the reliability of the Blood Alcohol Concentration (BAC) results.
