How sensitive are interlock breathalyzer?

Interlock breathalyzers are highly sensitive devices designed to detect alcohol in a person's breath. They typically can measure blood alcohol concentration (BAC) levels as low as 0.02% or lower, ensuring that even small amounts of alcohol are identified. The sensitivity of these devices is crucial for their effectiveness in preventing individuals with elevated BAC levels from operating a vehicle. Regular calibration and maintenance are necessary to ensure their accuracy and reliability.
