Calibration is a control and optimization process which configures the brethalyzer's software. Every breathalyzer might decalibrate in a process of normal use. That means breathalyzer doesn't perform tests correctly. For that reason these devices need periodic calibration that is readjustment to model template.

Calibration will prolong the life of breathalyzer

Frequency of calibration depends on many factors, e.g. type of breathalyser, intensity of use, age of the device or storing conditions. Calibration is a process which needs a specialized equipment and technical knowledge. It's based on performing tests with the breathalyser and outlining its efficiency. When the results differ from the reality, the software is being reset to the default settings. Calibration is performed using specialized machines, so called simulators. The process consists in performing tests on the device, which is working in service mode, on the samples of alcohol of known concentration. As a result, we need to adjust a correct response of measurement system to the model samples of certain concentration.

How often you should calibrate your device?

Depending on the type of breathalyser, calibration should be performed once per 6-12 months or once per 200-300 tests. Not performing a calibration may result in damaging the sensor. In such case, a warranty service is not valid and the cost of calibration is increased by buying a new sensor. Not following user's manual and using breathalyzer incorrectly may also result in quicker wear off and earlier calibration. Good example of faulty usage is performing the test just after drinking alcohol. When concentration of alcohol in the exhaled air is way bigger than the measuring range of the device. This leads to decalibration of the device or even a permanent damage to the tester. Regular calibration gives certainty that the measurements of the breathalyser are correct, independently of the date of buying the device. The device should not be used right after drinking alcohol. The program of the appliance assumes that exhaled air contains alcohol. Even the slightest traces of alcohol in mouth might cause incorrect reading. Additionally, performing a test before the alcohol is absorbed may cause burning of the sensor, as the concentration of the alcohol is way bigger than the measuring range.


Breathalyser is a sensitive and professional device which is influenced by body temperature. Temperature higher than one degree Celsius results in increasing the outcome of the test by 7%. The intensity of breathing results in opposite outcomes. For a person who performed a physical effort, a lower result will be obtained in comparison to someone who did not performed any physical activity. Chemical substances, such as oil paints, solvents, petrol, celluloid, cigarette smoke and many other which influence tested people for a longer period of time, will affect the precision of the breathalyser's indications. Mouthwash also contains alcohol which also affects results of tests.
