Common approaches, the results of the breathalyzer test:

The error of calibration
Since the engine, alcohol tester, and less time-sensitive. Proper calibration is needed for accurate results. Proof that the engine is adapted and / or services may influence the results.

Qualifying for the operator
Many countries have strict laws governing the use of force and maintenance of respiration. Since this device is very sensitive, operators are trained to adapt to different environments, the biological and physical conditions. The test is performed, the police jurisdiction can produce reliable measurements or inaccurate.

The absorption of Defense
The absorption of alcohol in the blood, it takes time. Some estimates indicate that, to compensate for two hours of the sale of alcohol in the body. Breath test during this period may lead to erroneous results, because alcohol is not uniform in different parts of the body. Furthermore, if alcohol were not included in the blood is not conducive to the level of drunk people.

Results of the breath test are based on the mathematical formula for the amount due to alcohol in the breath of alcohol in the blood. This formula is valid only if all environmental variables in origin. Proportion of alcohol in the breath, the level of blood alcohol is individual, and from time to time, changes in body temperature can also affect the results.
