On the Calibration
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 sticker 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.ace-technik.com.
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 guarantee expires, if you don`t pay attention to
the calibration ranges.
Which factors influence the measurement accuracy
The more often the device is used the more the zero point is influenced.
The higher the alcohol concentration is, the more the zero point is relocated.
Devices which are used rarely have a decreased sensibility, too.
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 calibra-
ted periodically.
Please also be aware of the several factors of influence on the measuring result
Alcohol amount
Age
Drinking habits
Size of the lung
Important notes on test execution and self-assessment
After the last sip of alcohol you should wait at least 15 minutes, as there may still be residual alcohol in
the oral cavity, which influences the measurement result. Also smoking should be avoided before a test,
as cigarette smoke harms the sensor.
