Each breathalyzer which you buy from ACE Instruments
can also be calibrated by ACE Instruments. Of course,
we also calibrate devices which were bought from other
contractors, as long as these devices are identical in
construction to the devices sold by ACE Instruments.
You can see the due date of the next calibration on the
calibration sticker placed on your breathalyzer. If the sti-
cker is missing, the calibration is to be done 6 months
after the purchase date: e.g. purchase date: 13.05. = next
calibration on the 13.11. and the next on the 13.05. of the
following year.
For a calibration service you can send the device to the
service address specified at www.alkomat.net.
Why is a Calibration Necessary?
The calibration is not mandatory, but the accuracy of
the sensor installed in the breathalyzer will decrease
steadily without a calibration and additionally guaran-
tee expires, if you don`t pay attention to the calibration
ranges.
Which Factors influence the Measurement Accuracy
Š
The more often the device is used the more the
zero point is influenced.
Š
The higher the alcohol concentration is, the
more the zero point is relocated.
Š
Devices which are used rarely have a decreased
sensibility, too.

Important Notes – EN
ACE Instruments recommends using the breathalyzer at
least once (1x) a week independently of having drunken
alcohol or not. To maintain the measurement accuracy,
the breathalyzer should also be calibrated periodically.
