How much does a breathalyser cost to recalibrate?
$30 to $75 for personal use models. Check our recalibration page to see how much your model costs (recalibration fees include return express postage)
How do I pay for my recalibration?
To make paying easy you have the following payment options: enclose a cheque or money order with your breathalyser or you can pay credit card or direct deposit.
Can I buy replacement mouthpieces?
Yes. Mouthpieces are available in packs of 10, 50 or 500. These are available through our website or in selected retail shops. Next time you send you breathalyser in for its recalibration, order some extra mouthpieces so you always have some on hand.
Do I still need to have my breathalyser recalibrated at 12 months even though I rarely use it?
To keep your breathalyser in top working order, it should be recalibrated every 200 uses or 12 monthly (whichever comes first) for personal use. Even if you only use your breathalyser a few times a year, its accuracy may start to drift after 12 months.
Do I have to post my AlcoLimit Breathalyser in for recalibrating?
Our service centre performs recalibration on all of our models and has a fast turn-around of approximately 2 days.
Several of our models have SRS (self-replaceable sensor) technology. This means you can order a pre-calibrated sensor and replace the sensor yourself. Its quick and easy, and has a simple easy to follow instruction sheet.
Can I get my breathalyser calibrated locally (interstate)?
To ensure quality control, all recalibrations and servicing are performed at AlcoLimit Breathalysers head office and service centre in Sydney. We only use calibrated specialised testing equipment and standardised comparison alcohol fluids to ensure the highest level of accuracy and precision in the recalibration of your AlcoLimit Breathalyser.
There is a funny error appearing on the display after my breathalyser counts down, what does this mean?
Some common ERROR messages that may appear on your breathalyser are:
BAT battery warning - replace batteries
SEN sensor warning return to AlcoLimit for servicing/ recalibration
FLO flow error turn unit on again and ensure you blow a firm consistent breath directly into the mouthpiece until you hear a double beep or click (depending on the model)
Please refer to your instruction manual for further possible error messages.
Why does my breathalyser slow down or pause during countdown when I turn it on?
When you first turn your breathalyser on, the countdown indicates the unit is warming the sensor up to approximately the same temperature as your breath (34 degrees). This ensures a more accurate measurement of your %BAC. If the unit has recently been used this may occur faster for subsequent readings. If the countdown becomes excruciatingly slow return it for recalibration because this indicates there is alcohol residue build up on the sensor.
What type of batteries should I use in my breathalyser?
All AlcoLimit Breathalyser models use Alkaline batteries (either AA or AAA). These are included with your initial purchase of the breathalyser. Always use a high quality brand (eg. Duracell) 1.5v Alkaline battery to get the optimum performance from your breathalyser. Some rechargeable batteries may work but they have various voltages. Rechargeable batteries with 2450 mAh should work fine.
Why have my partner and I recorded a different reading when we've had the exactly same amount to drink?
It is possible for 2 people to record differing %BAC even when they consume exactly the same amount of alcohol. Factors that may impact on this include gender, weight, metabolism, age, medications and whether food has been consumed. Using an AlcoLimit Breathalyser to measure your %BAC will allow you to make informed choices for your body type.
I've had 2 drinks in an hour and still get a 0.00 reading on my breathalyser, how is this possible?
Most people will record a low to mid level %BAC, but it is possible for a zero reading to be registered, as on average, a person will eliminate one standard drink of alcohol every hour. Factors listed above may also speed up the body's processing of alcohol.
How long must I wait after drinking alcohol before using my AlcoLimit breathalyser?
20 minutes. If you don't wait 20 minutes then you wont get an accurate reading. It takes 15-20 minutes for alcohol to be absorbed from your stomach to your blood and then comes out in your breath. Also the sensor will be unnecessarily saturated with alcohol vapour, resulting in recalibration (and sensor cleaning) being required earlier than scheduled.
If I get a reading of 0.049%BAC, is it safe to drive?
We don't recommend driving with ANY amount of alcohol in your system. Your alcohol level can continue to increase for up to 2 hours after you finish drinking because the alcohol in your stomach is still being absorbed into your blood stream. So it is possible for your alcohol level to increase after testing. We recommend you test your self at the 20 minute mark, then wait another 10 minutes and test your self again. You will then be able to determine if your alcohol level is decreasing or increasing.
