Breathalysers New Zealand offers a full calibration service for all products that we sell. It is very important to us that you have peace of mind in our products and feel supported by a local business.
Why do breathalysers require recalibration?
Recalibration is required as all breathalyser sensor accuracy inherently drifts over time. Additionally alcohol residue and intake particles build up on the breathalysers sensor until it reaches a point where it will affect the unit’s ability to take an accurate reading from the sensor.
Recalibration is typically a two-step process. The first involves flushing a special fluid through the sensor to clean it and the second is to test it at various %BAC levels to ascertain it’s accuracy. The unit is then reset at the various levels until it is back within the acceptable variance norms for the particular sensor type. Additionally the breathalyser airway may be serviced and cleared during this process.
The recalibration process needs to be conducted by a trained professional. Do not try doing it yourself as you will likely damage the sensor also the testing aspect requires specialist laboratory equipment.
Opening any Breathalysers Australia unit will void your warranty.
How often does my breathalyser require calibration?
This will usually depend on the time elapsed since the unit was purchased or last recalibrated. Other factors that increase the requirement for calibration frequency are volume of use, blowing unnecessarily strong concentrations of alcohol into the unit, or not waiting 15 minutes after consuming alcohol.
As a maximum guideline:
- Personal Use Breathalysers utilising Xtend® and BluFire® sensors need to be calibrated at least every 12 month
- Workplace Use Breathalysers utilising Xtend® and BluFire® sensors need to be calibrated between 6 and 9 months depending on the model and certification requirement
All of the breathalysers we distribute will come with a manufacturer’s recommendation for recalibration. These are also noted on this website under each of the product pages. Even if you don’t use your breathalyser for a prolonged period of time it’s accuracy will eventually begin to drift. This is why all recalibration recommendations come with a number of tests and a time guideline (whichever comes first).
Essentially higher usage or blowing high alcohol concentration samples, will build up alcohol residue on the sensor more quickly. When selecting which model of breathalyser you should consider that higher grade sensors (Xtend® or BluFire® fuel cell electrochemical) will have a substantially lower calibration requirement than semi-conductor sensors or lower grade fuel cell sensors.
How do I know when my breathalyser needs recalibrating?
We will email you at the maximum guideline date and remind you that recalibration is due. You may also notice your breathalyser may start taking much longer to warm up and consecutive readings could become inconsistent. This is not necessarily the case however and multiple tests may be closely grouped but ultimately be inaccurate. This is where quality plays a big part in the ongoing usability of your breathalyser and sending it in each cycle for recalibration and servicing which will ensure its longevity an accuracy.
How much does recalibration cost?
Once you purchase a breathalyser from Breathalysers Australia we will track the units serial number and run it through our calibration monitoring program. This will trigger us to send you an email to remind you as the unit becomes due for recalibration so you don’t have to worry about missing the time frame.
For Xtend® or BluFire® fuel cell sensors; BACtrack S80 Pro, BACtrack Mobile Pro, BACtrack Trace Pro, BACtrack Scout, C8 Smartphone and C6 Keychain the cost is $59.95 inc GST. This also includes the pickup and return courier to and from Brisbane, QLD.

Which breathalysers can Breathalysers Australia recalibrate?
Breathalysers Australia is Australasia’s only certified recalibration facility for BACtrack products. Additionally we are the only company that can perform this service globally for Australian and New Zealand sold BACtrack products.
Breathalysers Australia enforces a strict recalibration policy to comply with local AS3547 Australian Standards requirements. This Standard specifies that there must be complete traceability of the units serial number for it to be able to be recalibrated under the Standard. If the breathalysers serial does not originate from one of Breathalysers Australia’s facilities then we are unable to put our name behind the unit by recalibrating it. We do this not only to comply with the Australian Standard but also to ensure that substandard equipment is not being used to make potentially unsafe public decisions. Part of this consideration is that many leading brand breathalysers are replicated on the international market and can contain lower grade components.
Additionally if the unit originated from us yet the calibration period has lapsed for over 18 months we are unable to calibrate the unit. This is due to there being a substantially increased chance of the sensors performance being negatively affected to a point where calibrations will not hold accuracy for the required / specified periods of time.
