The accuracy of a breathalyzer depends on a variety of factors. Generally, breathalyzers are considered to be reliable if they are properly maintained and calibrated. However, there are some potential sources of error that can lead to inaccurate results. For example, certain medical conditions or medications can affect the accuracy of a breathalyzer reading. Additionally, environmental factors such as temperature or humidity can also impact the accuracy of a breathalyzer. It is important to note that the accuracy of any given breathalyzer will vary depending on its specific model and manufacturer.
In order to ensure accuracy, it is important to make sure that your breathalyzer is regularly calibrated and maintained according to the manufacturer’s instructions. Additionally, it is important to keep in mind that even if a breathalyzer is accurate when initially tested, its accuracy may decrease over time due to wear and tear or other factors.
