Has the mouthpiece to be replaced after every breath test?
For hygienic reasons, the mouthpiece should be replaced. In case of doing several
breath tests in a short time period an increased condensation may occur. In this case
you should make sure that the mouthpiece drys completely in the meantime.
Otherwise it can’t be ruled out that the former positive test results will be transferred
to the following test.
Is there a waiting period which has to be observed between the latest
consumption of alcohol and the breath test sample?
Remaining alcohol within the mouth may cause incorrect measurement values.
Incorrect measurements can also happen after the test subject burps or vomits,
drinks aromatic beverages (e.g. fruit juices) or uses alcoholc mouth spray. Therefore
a waiting period of at least 15 minutes after drinking or eating s.th. should be kept.
Has the Alcotest 3000 the same sensor technology like the professional and
more expensive breath alcohol measurement devices of Dräger?
Yes, the measuring accuracy and the sensor technology are the same. But: the
measurement range and the operating temperature are limited. The CE marking
“electromagnetic compatibility” (Directive 89/336/EEC) is also different. The CE
marking is limited for residential and commercial environments. The Alcotest 3000
has no data storage or an interface to a printer. It is designed for private use – for the
selftest – only.
Accuracy of the Alcotest 3000:
The devices are adequat to a class 5%-device.
Max. repeatability error with an ethanol standard
0 to 1,0 ‰ - +/- 0,05 ‰ >1,00 ‰ - +/- 5 % of the measurement value
0 to 0,540 ml/l - +/- 0,03 mg/L >0,50 mg/L - +/- 5 % of the measurement value
Is it possible for the user to calibrate the Alcotest 3000?
Calibration can only be performed in an approved Draeger service workshop, since
there the needed equipment is available. For the calibration of the Alcotest 3000 the
AlcoView 3000 software is required. For more information on the operation of the
software, the service manual may be consulted in DORIS.
