Behind the Numbers: How Alcohol Screeners & Breathalysers Measure Alcohol Levels
In a world focused on safety and responsibility, alcohol screeners & breathalysers have become crucial tools. From law enforcement to workplaces and even personal use, these devices help monitor Blood Alcohol Content (BAC) to prevent dangerous situations, such as impaired driving.
But how do these devices actually work?
Let’s understand how alcohol screeners and breathalysers measure alcohol levels, the science behind their accuracy, and their importance in promoting safety.
What Are Alcohol Screeners & Breathalysers?
Alcohol screeners and breathalysers are devices designed to estimate the amount of alcohol in a person’s bloodstream by analysing a breath sample. They provide a quick, non-invasive method for determining BAC, which can indicate intoxication levels. These devices have widespread use in several fields, from roadside law enforcement checks to employee safety monitoring and even for personal control after social events.
How Do Alcohol Screeners & Breathalysers Work?
Alcohol screeners and breathalysers function by measuring the concentration of alcohol in a person’s breath, which directly correlates with their BAC. The science behind these devices is grounded in the understanding that alcohol is absorbed into the bloodstream and then expelled through the lungs when exhaling.
Here’s how the process unfolds:
1. Sampling Exhaled Breath
When a person exhales into a breathalyser, the device collects and analyzes the air from the lungs. The key element it looks for is ethanol, the type of alcohol often found in beverages.
2. Conversion of Breath Alcohol to Blood Alcohol
The ratio of alcohol in a person’s breath is typically 2,100:1 to the alcohol in their blood. This means that for every 2,100 parts of breath, there’s approximately one part of alcohol in the blood. Breathalysers use this ratio to convert the breath alcohol reading into a BAC percentage.
3. Measuring the Alcohol Concentration
Different breathalysers use varying technologies to measure the alcohol concentration:
Fuel Cell Sensors
Common in professional-grade breathalysers, fuel cells generate an electric current when exposed to alcohol. The strength of the current is proportional to the alcohol level in the breath sample.
Infrared Sensors
These sensors measure alcohol by analyzing the absorption of infrared light by alcohol molecules in the breath. This method is highly accurate and is often used in law enforcement-grade breathalysers.
Semiconductor Sensors
These are typically used in lower-cost, personal devices. They measure alcohol by detecting changes in electrical resistance caused by alcohol molecules interacting with a semiconductor surface.

Factors That Can Influence Breathalyser Accuracy
While alcohol screeners & breathalysers provide a reliable measurement of BAC, certain factors can influence their accuracy:
Calibration and Maintenance
Like all precision instruments, breathalysers need regular calibration to maintain accuracy. Without proper calibration, readings can become skewed, leading to incorrect BAC estimates. Regular servicing, such as that offered by Quantum Scientific, ensures optimal performance.
Breath Temperature
Breathalysers are designed to work within a specific range of breath temperatures, usually around 34°C (93°F). If the breath temperature is significantly higher or lower, it can impact the device’s reading.
Mouth Alcohol
Residual alcohol in the mouth, from recent consumption or even the use of mouthwash, can lead to higher BAC readings. Professional breathalysers are designed to detect and adjust for this, but lower-end models might be more susceptible to false positives.
Time Since Last Drink
Alcohol takes time to be fully absorbed into the bloodstream, so testing immediately after consuming alcohol can yield a lower BAC reading than what will show up after full absorption. For this reason, breathalysers give the most accurate readings when used at least 20 minutes after the last drink.
The Importance of Alcohol Screeners & Breathalysers for Safety
Law Enforcement
One of the most common uses of breathalysers is in law enforcement, particularly for preventing drunk driving. Roadside breathalyser tests help officers quickly assess whether a driver is over the legal limit, thereby reducing the risk of accidents and fatalities on the roads.
Workplace Safety
Many industries, especially those with heavy machinery or hazardous environments, rely on alcohol screeners to ensure that employees are fit for duty. These devices help prevent accidents caused by impaired judgment or slower reaction times due to alcohol consumption.
Personal Use
Increasingly, individuals are using personal breathalysers before getting behind the wheel or making important decisions after consuming alcohol. Portable, affordable models make it easy for anyone to check their BAC and make informed choices about driving or operating machinery.
