Recalibration Service

The Andatech AL 6000 Pro and AlcoSense Precision have 12 MONTHS FREE UNLIMITED CALIBRATION from the date of purchase. Terms, conditions and guidelines apply, CLICK HERE FOR MORE INFO! 

All breathalyser products distributed by ANDATECH have a recalibration function.  The recalibration feature allows the breathalyser to retain its accuracy even after hundreds of tests. Other products that do not offer recalibration tend to lose accuracy over time and will not give accurate readings. The recalibration feature may provide greater accuracy in readings with increased reliability.

Unfortunatly we currently are unable to offer calibration or support for Easy Check, Draeger, Guardian, Sober Check SC3000, AlcoLimit, Alcolyzer, Breathe Check, Alcomate or Alcohawk, HH1 Alcolizer. We would love to offer our assistance, considering we have the assembly, parts and man power to so, however we dont want to run the risk of 'rocking the boat' with other companies. We realise how silly may sound, but at the end of the day having a fully trained technician who is familiar with the specific unit conducting the calibration will ensure better accuracy and better safety for your loved ones.

What is Calibration?

All breathalysers indicate BAC (Blood Alcohol Concentration) level based on the information stored in the sensor’s memory. Exact values of certain BAC levels are stored so that the sensor can provide the most accurate readings. Over time, however, these stored values tend to lose accuracy as more tests are conducted. The sensor itself and the stored sensor values tend to deteriorate over time and with more tests, affected by external variables. In order to restore the sensor readings to maintain better accuracy, all breathalysers must be recalibrated to refresh sensor values as to allow the breathalyser to obtain better accuracy of readings.


How often should you recalibrate your breathalyser?

For AlcoSense Mini, recalibration is recommended every 6 months for the standard user (4-5 uses per week). For heavier users it is recommended every 3-6 months.

For Andatech AL6000 Pro, recalibration is recommended every 150 uses or every 4-6 months. The sensor needs replacement every year or 500 uses in total. The cost of sensor replacement is included in calibration.

For AlcoSense® Precision, recalibration is recommended every 1 year. Sensor replacement is not needed with a fuel cell breathalyser.

How do you know when your breathalyser needs recalibrating? 

1. When you turn on the unit and the displayed number of uses exceeds 200. (Andatech AL6000 Pro only)
2. When any of messages "SEN", "ER-4" or "CAL" appear on the display after count down. (Andatech AL6000 Pro only)
3. When your unit is more than 6 months old or it has been over 6 months since it was last recalibrated. (AlcoSense Mini and Andatech AL6000 Pro only)
4. When the unit starts significantly higher readings than expected.
5. When you turn on the units and 3 LED lights are on with nothing displayed on the screen.

Can we recalibrate other breathalysers?

Andatech is no longer supporting any other breathalyser. All old breathalyers are recommended for an upgrade to Andatech AL6000 Pro. Any breathalyser purchased from Online Auction will not be supported unless they are our authorised reseller, Please check with the seller before confirming the purchase.

How do you send your breathalyser back for recalibration?
