AlcoSense offers a range of personal and workplace breathalyzers, each with different functions and benefits. With so many breathalyzers, you are often left wondering which breathalyzer to buy! Well, we hope the Breathalyzer Selector tool has helped to guide you towards the best breathalyzer for you.

Personal breathalyzers and workplace breathalyzers differ not only in price range but also in functionalities. Personal units are more compact, simple to use, and straightforward, whereas workplace units are designed for testing multiple people and have added functionalities to keep test records, export data, and even print results. Depdnding on requirements, some personal breathalyzers can also be suitable for workplace testing, especially if only a small number of people need to be tested. 

How accurate do you need your breathalyser to be?

As explained in our article on how a breathalyser works, breathalysers generally use two types of sensors - semiconductor sensors and fuel cell sensors.

Personal breathalysers generally use semiconductor sensors because they are more affordable (usually around $200 or less). However, semiconductor technology is less accurate (usually with an accuracy range of +/-0.01%BAC) and are not alcohol-specific, meaning they can pick up traces of substances such as cologne or mouthwash when giving a reading.

Semiconductor breathalysers will still remain accurate when calibrated regularly (every 6 months), and are generally only suitable for testing one person or a few other people, like friends or family, on a night out. They do lose stability over time and have a shorter working like than fuel cell breathalysers.

If you need something that gives you a good estimate of your BAC range and you don't need something extremely accurate, then a semiconductor breathalyser like the AlcoSense Pro or the AlcoSense Zenith is a smart and affordable choice for you. 

If you need something much more accurate for personal use and you don't mind spending the money, go for a fuel cell breathalyser instead. Fuel cell technology has advanced in recent years and their prices have started to decrease as well, making them more affordable for consumers. Fuel cell sensors offer much higher accuracy (with an accuracy range of +/- 0.005%BAC), a longer working life, and more stability over time even with multiple tests. More importantly, they are alcohol-specific and will not be affected by other substances in your breath.

For personal use, we recommend the AlcoSense Stealth and AlcoSense Zenith+ - both are highly accurate for personal use and great for low volume professional testing as well. For new drivers and old drivers, we also have the AlcoSense Verity, available in five colours and designed with a built-in mouthpiece for convenient testing on-the-go. 

Do you need Australian Standards AS3547 Certification?

To get Australian Standards AS3547 certification, a breathalyser is tested independently by SAI Global for their accuracy and reliability. Breathalysers with this certification are proven to perform better than other breathalysers in the market that are without it. The certification also shows that the breathalyser is serviceable and well-supported through a strict control process as a safety device.

Most workplaces require their breath testing device to carry this Certification. The top choice is the AlcoSense Precision+ which provide fast and simple breath testing, or the more advanced AlcoSense Prodigy, which has various capabilities including keeping data, printer compatibility and USB functionality. The Prodigy is ideal for workplaces that employ a very strict alcohol policy, such as mining and construction sites, fleet and aviation companies, medical clinics, hospitals, rehabilitation centres and of course, law enforcement.

All AlcoSense breathalysers go through strict testing procedures before we introduce them to the market, and we are constantly improving and increasing our standards on quality. All our breathalysers are serviceable and are calibrated by our in-house technicians under a strict controlled process. 

Other factors to consider when buying a breathalyser

Convenience - if you need your breathalyser every day, or know you'll be too busy to send it back every 6 months for calibration, get a breathalyser with a replaceable sensor - such as the AlcoSense Zenith or AlcoSense Zenith+. With the replaceable sensor, you don't have to send your breathalyser back for calibration, so as long as you have a spare calibrated sensor on hand, you'll never have to be without your breathalyser.

Calibration - all breathalysers need to be calibrated to maintain their accuracy. They generally need to be calibrated every 6 months for personal breathalysers, or one year for industrial breathalysers. If you don't get your breathalyser calibrated at the recommended frequency, you will find that it gives you false readings or very high readings. Do not buy a breathalyser that is not serviceable or cannot be calibrated. Steer away from the $20 keychain breathalysers being sold on the internet, as these are usually inaccurate and cannot be calibrated at all.

Extra features - Do you need something simple, or must you have a unit that keeps past test results? Check the breathalyser's features and functions before you buy, or just contact our friendly team on 03 8877 0700 or on email to ask for assistance and recommendations.
