how-do-breathalysers-work

Alcoholic beverages are commonly enjoyed worldwide. However, alcohol is also the most abused despite being a legal and controlled substance. Studies show that intoxicated driving causes 250,000 out of the 1.25 million road fatalities in accidents worldwide. Consequently, regular breath testing with a breathalyser is becoming an essential part of our working adult lives. Breathalysers are the most accessible and cost-effective ways to test for alcohol. But how do breathalysers work? By analysing a breath sample, breathalysers determine a person’s Blood Alcohol Concentration (BAC). Using these methods, companies and law enforcement can identify unsafe drivers.

Furthermore, advances in sensor technology have made it possible to buy personal breath test kits that people can use at home and before work. Moreover, these breath tests are quick, easy to perform, non-invasive and hassle-free. BACtrack breathalysers at Breathalysers Australia there the most effective and convenient breath testing devices in the market today.

How Do Breathalysers Work – A Short History

How do breathalysers work? And how did they come to be? Many people look for an adequate breath testing kit to fit their needs. Fortunately, modern breathalysers are compact and easy to use compared to previous models. The first breath test kits were complicated devices that included a balloon and a tube of yellow crystals mounted on a desk. The subject would then blow into the balloon to release air into the tube. These yellow crystals would change colour depending on the amount of alcohol in the system. Fortunately, we are past the days of these balloons and copper tubes. Present-day breathalysers are cost-effective, reusable and dependable.

People need not worry too much and look up “how do breathalysers work”. All a modern breathalyser needs is a breath sample blown into a sterilised mouthpiece for an accurate BAC measurement. In addition, this accessibility allows anyone from your average person to office employees to perform an accurate BAC reading. Furthermore, these new breath test kits allow for accurate BAC readings anywhere and on the go. Breathalysers Australia provides police-grade breathalysers and other breath test kits for personal and workplace use.

How Do Breathalysers Work Exactly?

The question of “how do breathalysers work” is an essential one to ask when looking for a personal or professional breathalyser. During a breathalyser test, the user blows for around 5 seconds into the device. The volume of air required will need to come from the deep lung area, where the device can get the most precise BAC measurements. High-performance breathalysers will have an effective breath capture system. Consequently, the device will only execute a reading when the user provides it with the right amount of air. In addition, the device will advise the user to try again if the breath sample is not adequate. 

For an accurate reading, a heating element within the breathalyser’s sensor will heat to 34 degrees Celsius before the user provides the sample. This temperature is approximately the same as the temperature of a person’s breath for improved accuracy. Once acquired, the breath sample passes from the mouthpiece, into the intake tube and over the breathalyser’s sensor. This sensor then measures and calculates the result to be viewed on the digital display. Simply put, that is the answer to “how do breathalysers work”. Breathalysers such as the BACtrack breath test kits ensure quality and precision when providing BAC readings.

Understanding BAC, or Blood Alcohol Content

“What is BAC” is likely another follow-up question to “How do breathalysers work”. Understanding BAC is essential when looking for the right breathalyser. The Blood Alcohol Content is a metric used to measure the amount of alcohol in the bloodstream. Breathalysers calculate BAC in grams for every 100ml of blood. For example, a 0.05% BAC equals 0.05 g per 100ml of blood. Consequently, the higher the BAC level, the more a person becomes intoxicated. Furthermore, our bodies react differently to alcohol consumption. Hence, BAC and the exact intoxication levels are not easy to measure without a precise method. Luckily, current-day personal breathalysers measure BAC conveniently and efficiently. Such precision is essential as the several factors that affect BAC include:

  • Body composition – body mass index, weight and fat content significantly impact BAC. People with more body fat and diminutive stature will likely experience quicker intoxication.
  • Age – as people age, metabolism and alcohol processing capacity slow down. 
  • Alcohol concentration – each type of drink will have a different alcohol concentration.
  • Medications – prescription drugs and other substances sometimes react with alcohol and overstate the BAC results from a test.
  • Stomach content – a full stomach can help slow the absorption of alcohol into the body.
  • Gender – compared to men of the same weight, women tend to have higher proportions of body fat. In addition, the hormonal differences between men and women affect alcohol metabolism.
  • Diet – specific diets, such as low-calorie and low-carbohydrate diets, may trip up the BAC and cause false positives on less accurate breathalysers.
