Measurement accuracy according to the alcohol tester accuracy study of the Vienna University of Technology from October 2015. Here, 5 measurement reference points (0.00, 0.10, 0.25, 0.40 and 0.60 per mille) were tested with 5 identical measuring devices and 10 repetitions each (excluding the manufacturer) in the laboratory. In total, the device type was tested 250 times in the laboratory of the Institute for Analytical Chemistry of the Vienna University of Technology, under the direction of Univ.
