Does Keychain Breathalyzer test provides lesser Accuracy

Keychain breathalyzers are available for consumers’ use. These are commonly used to estimate the blood alcohol content (BAC) of a person. However, a Keychain Breathalyzer test provides lesser accuracy than those used by police officers for field sobriety tests.

A number of keychain breathalyzers have limited maximum range for the measurement of alcohol in the breath. Some products have a threshold of 0.05 only, whereas the level for a blood alcohol content to qualify for a DUI offense should be 0.08 and above. Other keychain breathalyzers are also disposable. This means that each time you need to blow, you must make sure to discard the breathalyzer and never use it again.

While most keychain breathalyzers make use of semiconductor-based sensing technologies, a few are already adopting the police technology by using a fuel cell sensing system to yield better and more accurate results. As an effect, breath alcohol analyzers like them are more expensive than the regular ones.
