Re-calibration is required as alcohol residue builds up on the breathalysers sensor over time until it reaches a point where it will start to drift and become inaccurate. Re-calibration is 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 ensure that the units readings are back within its acceptable range. Additionally the breathalyser airway will be serviced and cleared.
This process needs to be conducted professionally. Do not try doing it yourself as you will likely damage the sensor. The testing aspect also requires specialist laboratory equipment. Opening any Breathalysers Australia unit will void your warranty.
This will depend on the unit itself, the amount of usage, and the amount of time since the units last calibration. 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 quicker. Higher grade sensors (fuel cell electrochemical) will have a substantially lower calibration requirement than a semi-conductor sensor.
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 longevity.
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 electrochemical fuel cell sensors; BACtrack S80 Pro, BACtrack Mobile Pro, and BACtrack Trace Pro the cost is $55 inc GST. This also includes airway servicing and the pickup and return courier to and from Newcastle, NSW.

We do not. The majority of leading brand breathalysers are replicated on the international market and can contain lower grade components. We therefore do not want to put our name behind anything that hasn’t met our strict quality criteria and that we know the origins of. Also some units have specific calibration requirements that we may not necessarily have the equipment to perform. Please do not send your unit to us without having contacted us first. We record all of our units serial numbers before they leave our warehouse. We back our products 100%.
