Breathalyzers with anti-deception

Anti-deception

— a function that allows the breathalyzer to automatically control the correctness of the measurement procedure. To do this, the device analyzes the volume of actually exhaled air, and if this volume is not enough for effective analysis, it reports that the measurement needs to be repeated. As the name implies, the main purpose of anti-cheating is to prevent measurement manipulation, when the test person tries to artificially lower the readings by “blowing out” an insufficient amount of air. Although, of course, this function will be useful if the user violates the procedure unintentionally.
