Which Breathalyzer is Right for Your Organisation in Australia?


Whether you are considering investing in a Breathalyzer for safety, legal or medical reasons there are a few key criteria that come into play in helping you determine the best product for your company’s needs. 

 The legalities:  Your Company is legally responsible and legally liable for any injuries, accidents and deaths incurred due to alcohol consumption when a person in your employ or on your premise is deemed responsible for an incident.  Whether your business is transportation (car/truck/bus/train/ plane or ship), mining, construction, or a plethora of other businesses that involve the use of company cars or equipment or you own a restaurant, lounge or bar, the law holds YOU responsible for anyone consuming liquor on your premises or while operating your equipment.

The safety factors correlate directly with the legal issues.   If, for example, an employee is operating a crane on your building site while under even the slightest hint of alcohol and there is an accident the company that supplied the crane and the crane operator as well as the construction company responsible for the site are all responsible for the safety of workers and are legally responsible for any mishap.

The medical profession entails two variants of the legal and safety aspects.  Physicians and staff need to determine the amount of alcohol, if any, is in a trauma patient’s system prior to administering any care or medication and hospitals, clinics and doctor offices need to monitor their staff.

Andatech (AlcoSense) is the premier manufacturer and industry leader in personal and professional breathalysers in Australia.  We recommend three of Andatech breathalyzers for both business and industrial use. Your choice will be determined on your needs and requirements.

For industrial use we recommend a using a fuel cell unit at a minimum, these units only respond to alcohol, unlike semi-conductors which will show a result in the presence of certain foodstuffs. In addition to this, our range of professional breathalyzers are all designed for use in OH&S, which means

 The casings are designed so the air flow goes through the unit rather than inside it preventing the build-up of saliva within the unit

  • The mouth pieces are able to be attached and removed hygienically without the operator touching them
  • The sensors are large fuel cells with greater accuracy, stability and durability.


Our three recommendations:


 Criteria for selecting the most appropriate breathalyser:

 Accuracy - All of our recommended Andatech units are very accurate with a .005% at a reading of .100% Blood Alcohol Content, as they use Fuel Cell Technology.  

 Number of Tests – This means how many times the unit can be used accurately before sending it away for Re-Calibration.

  • If you are doing a low number of tests (1-10 per week) the Zenith Plus, effective for 500 tests or 6 months prior to re-calibration, is ideal.  
  • If you are doing 10-20 tests per week consider the Precision Plus, effective for 1,000 tests or 12 months prior to re-calibration.
  • If you are doing 20-50 tests per week consider the Prodigy, 1,500 tests or 12 months prior to re-calibration.
  • If you are doing more than 50 tests per week then we would suggest multiple units of the  Prodigy.

Note: If you are following the AS3547 Standard to the letter, then you should Calibrate every 6 Months.

Passive Mode Testing – is when a mouthpiece is not required; the person being tested merely speaks to the unit. The units detects the presence of alcohol on the breath; you then have the option of conducting a second test with a mouthpiece for a numeric reading of the blood alcohol content. (BAC). You can do this with the Precision Plus or the Prodigy.

Warm Up and Refresh Time – If you need to conduct numerous tests in a short period of time it would be wise to consider either the Precision Plus or the Prodigy Units

Need to Store Results – If you need to retain test results, the Prodigy is your best choice. The Prodigy unit stores up to 10,000 entries and can be connected to a PC and the results uploaded to the computer

Connect to a PC – The Prodigy can connect to a PC, so you can upload results for Analysis and Reporting.

Australian Standard AS3547 – The Zenith Plus, Precision Plus and the Prodigy Breathalyzers are compliant with AS3547.

Budget – Proper safety precautions can save years of court battles, untold dollars and more.  If your business could benefit from and protect you by having a breathalyser policy and testing n force it is far wiser to invest in safety now and upgrade as needed.

Why Andatech (AlcoSense)?

Andatech breathalysers has helped pioneer the consumer market for breath alcohol testers. Andatech first offered breathalysers in to the Australian market in 2003 and has since expanded the product line to include highly accurate fuel cell-based breath alcohol testers for professional and industrial use. Andatech alcohol testers are used by law enforcement, safety inspection and numerous health clinics, hospitals, construction companies, aviation businesses, mining sites and other professional organisations for both evidential alcohol testing and alcohol screening applications.

In 2004, Andatech was the first company in Australia to receive the Australian Standard AS3547 for a personal hand-held breathalyzer under $200.  Andatech breathalysers have been accredited with ISO9001 Quality Management System for the sales, distribution and service of breathalysers in Australia. Andatech is the industry leader in personal and professional breathalyser distribution through both wholesale and retail channels.

What is the difference between a fuel-cell breathalyser sensor and a semiconductor sensor?

The advantage of semiconductor sensors is in price; they are very inexpensive to make.  The disadvantages are they use a lot of power; take time to warm up; are less stable over time, and can give false positive readings in the presence of some foods and sugars that have a chemical structure similar to alcohol.

The advantages of fuel cell sensors are they use no power; are ready for use almost instantly; are more stable over time, and rarely give false positive readings.  The usual disadvantage of fuel cell sensors is their cost.  To counter this issue, Andatech spent years developing its own patented fuel cell sensor technology that has resulted in a sensor that is significantly less expensive to make when compared to conventional fuel cell sensors, yet is reliable and accurate.


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 use. In order to restore the sensor readings and to maintain optimum accuracy, all breathalysers must be recalibrated at set intervals predicated on both frequency of use and elapsed time.

What does Australian Standard AS3547 mean?

The majority of Andatech's breathalysers have passed and are certified to Australian Standard AS3547.  This means that the breathalyser has been tested for both accuracy and reliability. Certification under Australian Standard AS3547 means the product has been proven to substantially outperform breathalysers on the market without the certification.  Australian Standard AS3547 certification also means the breathalyser is recognized as a safety device and is serviceable and well supported through the strictly controlled process for any safety product.
