Studies of TU Vienna


In two scientific studies, the measurement accuracy of breath alcohol testers was checked. The results were made available by the Vienna University of Technology at the end of October 2015 and in January 2019.

In the 2015 study, the scientists of the Vienna University of Technology tested 5 identical measuring devices of the same mobile model and 10 repetitions each in their laboratory using a total of 5 measurement reference points (0.00, 0.10, 0.25, 0.40 and 0.60 per mille). The entire procedure was carried out to the exclusion of the manufacturer.

On the basis of the aforementioned procedure, the individual device types were tested 250 times in the laboratory of the Institute for Analytical Chemistry of the Vienna University of Technology, headed by Professor Dr. Erwin Rosenberg. You will find detailed details on the test procedure and the test results in the complete study, which ACE GmbH Germany is pleased to provide in the PDF document.

The study, published in January 2019, was based on the same criteria, but with different alcohol testers.

The aim of the study:
The study, which was carried out in a laboratory of the Vienna University of Technology, should determine the reliability and measuring accuracy of mobile breathable test equipment in a controlled environment. The study was initiated by ACE since in the past there was no scientific study on the measurement accuracy of the breathable testers available on the market and mobile. ACE offers various alcohol testers since 2003 and constantly optimized the devices over time. The experience of ACE as well as the social treatment of alcohol show that there is a need for alcohol testing equipment in non-police use.

Alcohol and society:
The consumption of alcohol takes place worldwide in different manifestations and in some places almost already to the custom, for example as soon as within traditional events and in a social circle the one or other alcoholic drop flows. If you consume alcohol, you sooner or later will notice the stimulating effects and at the same time you have to be aware that even small amounts of alcohol restrict the perception and reactivity. This also reduces the ability to steer a vehicle safely.



Alcohol and law:
It is well known that legislators worldwide have set country-specific alcohol limit values ​​which, when exceeded, are considered to be unsafe for driving a car or operating a machine. Therefore, if the police finds you sitting behind the wheel of a vehicle and if you have a higher blood alcohol level in an alcohol test than permitted by the law, you have to expect serious legal consequences. With breathalyzers the blood alcohol level is determined by the alcohol content in the breath of a test person.

Reliable maesurements:
A reliable test procedure requires the police to use precise measuring methods and measuring instruments. In the meantime, more and more private users have become very interested in alcohol testing devices which enable them to measure the degree of alcoholisation in a precise, simple manner and at a comparatively low price. They themselves want to be able to measure their breath content as an estimate of the blood alcohol concentration.


ACE Breathalyzers convince:
Within the scientific study carried out by the Vienna University of Technology, the ACE was able to test breath alcohol testers with measurement accuracies of 98% to 99%. The majority of the alcohol testers tested in the study were in no way inferior to the police equipment of the well-known manufacturers Dräger and EnviteC with regard to measuring accuracy. The present study has shown that ACE alcohol testers provide very reliable guidelines on the degree of alcoholisation. It does not matter whether the alcohol test equipment is used in the evening before the planned home journey or the next morning to determine the residual alcohol.

About laboratory studies:
A laboratory study is a scientific method by which a certain hypothesis is tested by means of laboratory experiments and under controlled conditions. Compared to field studies, which, as the name implies, are carried out in the natural environment of the research object, laboratory studies are carried out in an artificial environment created especially for the respective study, which corresponds to a largely closed experimental environment.

Advantages of laboratory studies:
Comparing laboratory studies with field studies, the comparing ones are distinguished by the fact that the different influencing variables in the laboratory are easier to observe than outside the research facility used. This is valid not only for the actual experimental arrangements, but also for the variables influencing the experiment (such as potential disturbances). In addition, it is only possible in the laboratory to systematically change individual variables and to check the effect of the change in a controlled manner.


In the field of alcohol measurement technology research has been carried out and developed for many years. The measuring instruments for the determination of the breath content are becoming more accurate and more stable. At the same time, the electrochemical sensors installed in the breathalyzers have a very good quality. However, a high quality does not necessarily mean a high purchase price.

The alcohol test equipment from ACE proofs this because according to the study by the Vienna University of Technology, in terms of measuring accuracy they are by no means inferior to the police equipment of Dräger and EnviteC.

ACE breathalyzers convince with measurement accuracies from 98% up to 99% and thus provide very reliable guidelines for the degree of alcoholisation - whether in the evening before driving home or on the next morning where a breathalyzer helps to determine the residual alcohol.
