What is a common alternative to the Intoxilyzer 9000 for breath testing?

The Alcotest is a common alternative to the Intoxilyzer 9000 for breath testing because it operates on similar principles of measuring blood alcohol content through breath samples. Both devices utilize infrared spectroscopy technology, which allows them to analyze the chemical composition of the breath. The Alcotest has been widely used in various jurisdictions and is known for its reliability and accuracy. This makes it a viable option for law enforcement and other agencies tasked with measuring impaired driving.

The other options, while they might be familiar to some, do not have the same standard presence or acceptance in law enforcement as alternatives to the Intoxilyzer 9000. The Breathalyzer, for instance, is a well-known brand but may not utilize the same technology as the Intoxilyzer 9000. The SoberTest and SmartCheck are less recognized and do not have the widespread use or scientific backing of the Alcotest.
