Calibration of Breathalyzers 

1. Why do we calibrate?  
   1. So that the breathalysers remain accurate, one must readjust the device on a regular basis = calibration.
   2. The crucial factor is not, like often incorrectly supposed, how often the device  is used. Time plays an important role: With devices that are frequently used, the “Zero” position can readjust itself. With devices that are not used on a regular basis, or devices that sit unused for a long period of time, the sensitivity decreases. Regardless of use, it is necessary to calibrate breathalysers within certain time intervals, i.e. allow for calibration.
          
2. Calibration by ACE  
   1. All breathalyzers that can be acquired from ACE can also be calibrated by ACE.
   2. The next due date of calibration can be seen on the label attached to your breathalyzer device.
   3. If the calibration label is missing, then the next due date for calibration would be within 6 months of purchase, or double from the date of purchase. (E.g. purchase date 13.5, calibration is then due on 13.11 and the second calibration would then be due on13.5 of the following year).   
       
3. How to calibrate your device with ACE
   1. Print and fill out the return calibration voucher.
   2. Send your breathalyzer with the calibration order form (please affix stamp) to the listed address. Please pack your device carefully, so that there can be no damage during transportation.
   3. You will receive your calibrated breathalyzer within approximately one week
