Keychain Breathalyzer
Most law enforcement officials are trained in identifying a drunk driver. The most common tasks drunk drivers are asked to perform after they have been pulled over are coordination activities and speech and/or memory evaluations. When officials need on the spot results with verifiable evidence, a breathalyzer screening provides the most timely and conclusive results.
In the past, breathalyzers were not only unavailable to the public, but they were costly and difficult to use. The products available today combine quality and affordability. A key chain breathalyzer is one of the most convenient models available, being small enough to carry with you at all times. The keychain breathalyzer allows for a quick and accurate check of your blood alcohol level.
These are ideal for those who go out and drink on a regular or irregular basis, but want a reasonable and affordable way to check their alcohol level. For these people a breathalyzer is one of the most responsible purchases a person can make.
The manufacturer will list recommendations for using and cleaning each breathalyzer. Some will require regular maintenance and cleaning, others will require little, especially if they are used infrequently. Frequency of use should not determine if the recommendations for cleaning and maintenance are followed though. Maintaining your keychain breathalyzer is easy to do.
Even without regular use, the ability of the breathalyzer to sense alcohol levels accurately may become less reliable over time. This is the main reason why re-calibrating the breathalyzer is so important. Over time, results can be less accurate as the sensor loses its effectiveness.
Most manufacturers recommend recalibrating a breathalyzer at least once a year, or sooner if you fell that you are getting inaccurate results. Almost all manufacturers of breathalyzers will calibrate your breathalyzer for a minimal charge, usually around $20. You will generally be responsible for the shipping costs to the calibration center.
