Product Servicing - Recalibration

If the information you require is not below, see our FAQ page or please call us on 1300 667 661 and our technicians will assist you over the phone.



Why Do I need To Get My Breathalyser Recalibrated and How often?

We recommend recalibration every 1-6 months for professional use models and 6-12 months for personal use, depending upon usage levels. eg. For personal use, if you use your AlcoLimit 2-3 times per week then recalibration is recommended every 6 months. If you use it less frequently, say every 1-2 weeks, then recalibration is required every 12 months. All breathalysers should be recalibrated at a minimum of every 12 months irrespective of use because the calibration setting can drift over time whether or not it is used.

If you are a heavier drinker and blow high levels of alcohol vapour into the sensor or share your AlcoLimit with your mates on a weekend, then you will need recalibration sooner than 6 months.


For workplace use, your breathalyser must be calibrated in accordance with the manufacturer's specifications as indicated in your user manual. This is required to maintain the Australian Standards certification on your device.

If you have any doubt as to the reading you are receiving from your AlcoLimit then please send your unit to us to be recalibrated. Breathalysers are sensitive equipment and need regular maintenance to maintain their specified accuracy.

Recalibration is required because alcohol residue builds up on the sensor and this must be cleaned due to it affecting the accuracy of the device over time. The sensor needs to be cleaned professionally. Do not try and clean it yourself as you may damage the sensor and the device will not work properly. A special fluid needs to be flushed through the sensor and the electronics need to be reset during recalibration.


How Do I know When My AlcoLimit Needs Recalibration?

Your breathalyser will take much longer to warm up - over 2 minutes, consecutive readings will be inconsistent or unexpectedly high eg. 3 in a row varying greatly (this occurs because there is a build up of alcohol residue on the sensor and it cannot read your breath properly).

If your AlcoLimit displays SEN, or any other errors please send it back to us for servicing.

Unlike other breathalysers, Alcolimit will not shut down after a certain number of uses. You will still be able to use your AlcoLimit but please be aware that if you fail to get it recalibrated in the time periods stated you will not be getting the most accurate readings and may void your warranty.

The following warranty is provided with all AlcoLimit Breathalysers as required under Australian Consumer Law.


"Manufacturer warrants for one calendar year the product to be free from defects in workmanship or materials (excluding calibration) in normal service from the date of purchase. Manufacturer’s obligation under this warranty is limited to replacing or repairing the unit if returned along with proof of purchase. This warranty is void if unit has been tampered with, misused, dropped, maliciously damaged or used for any purpose other than that intended.

The cost to return the unit to the manufacturer’s service centre is at the expense of the consumer. The consumer is welcome to drop the unit off at our service centre in person. The consumer must contact our customer service centre prior to returning the unit to us to enable our technicians to diagnose the fault over the phone.

Instant Self-Servicing on-the-spot!

The inconvenience of sending your breathalyser for regular recalibration is now a thing of the past with our new Self-Replaceable Sensor (SRS) technology.


Look for the SRS symbol on selected models for this option.

Self-replaceable Sensor Technology (SRS)

The inconvenience of sending your breathalyser for regular recalibration is now a thing of the past with our Self-Replaceable Sensor (SRS) technology. Simply order a pre-calibrated sensor, click out your old sensor and click in the new one and you're ready for testing.

AlcoLimit Breathalysers are the leaders in self-replaceable sensor technology in Australia. The general public have used this technology in our Enforcer 2 breathalyser since 2007. We have also rolled this technology out to selected breathalysers in our range of workplace breathalysers.


There are 2 types of sensors used for SRS technology:


- Semi-Conductor Sensor

- Electrochemical Fuel Cell Sensor


Semi-Conductor Sensor (disposable type) - this type of sensor is for low volume testing, is inexpensive and generally discarded after use. Simply remove the used sensor and replace it with a new pre-calibrated one. The used sensor is thrown away.


Electrochemical Fuel Cell Sensor (recalibration type) - this type of sensor is for heavy duty use, is more expensive and can be recalibrated. We recommend you always have a spare sensor on hand, remove the used sensor and replace it with the freshly calibrated one. Then send the used sensor to our service centre for recalibration.

SRS Technology is currently available for the following models:

AlcoLimit Enforcer 2 Breathalyser - sensor cost $49.50    (disposable type)
AlcoLimit Enforcer 3 Breathalyser - sensor cost $
49.50    (disposable type)

AlcoLimit DUI Wallmount Breathalyser - sensor cost $49.50    (disposable type)
AlcoLimit RBT Wallmount Breathalyser - sensor cost $225   (recalibration type)

All prices above include overnight freight to you via Australia Post.

When your breathalyser is due to be recalibrated, simply order a replaceable sensor module from our technicians. They will calibrate the sensor module on the day you place your order and overnight express it to you.

Once you receive it, simply follow the instruction page provided with the sensor or view the applicable
servicing video below.
