Disposable Breathalyzer: What It Is, How It Works, And How To Use

20 November, 2023

A disposable breathalyzer is a single-use tool that measures the alcohol content in the breath of the user. It works through a chemical reaction that occurs when the breath is blown into the device. To use it, one needs to blow steadily into the breathalyzer and wait for the results to be displayed. It is a simple and easy-to-use tool for individuals who want to check their alcohol levels quickly and conveniently.

Individuals frequently use breath tests before driving. Someone who has been out may lack precise awareness of their alcohol level. Although they might feel confident about their ability to drive, there is a likelihood that they underestimate their level of intoxication. Utilising a single-use breathalyzer enables an individual to objectively measure their blood alcohol levels for safety purposes. This article will provide information on disposable breath testers, including their functionality and proper usage.

What is a Disposable Breathalyzer

A disposable breathalyzer is a portable device that assesses the presence of alcohol in the system. It operates by analysing a breath sample from an individual and delivering a measurement of their Blood Alcohol Concentration (BAC). Although it operates similarly to a conventional breathalyzer, this tool is intended for single use.

Additionally, a single-use breathalyzer is a plastic tube with indicator agents that react upon detecting alcohol in the breath. This testing method proves highly advantageous for people wishing to assess their alcohol concentration levels. This type of breathalyzer is particularly beneficial for those who need to measure their BAC before engaging in specific activities.

Numerous incidents of accidents and injuries have resulted from alcohol impairment. This underscores the importance of having a disposable breath-testing device for immediate use. Moreover, this tool can efficiently ascertain the suitability of an individual for tasks like driving, working, or managing sensitive responsibilities. Nonetheless, this approach encourages responsible and safe drinking practices for all.

Benefits of Owning and Using One

  • Provides a quick and easy way to assess personal BAC and stay within the legal limit.
  • Reduces the risk of impaired driving by allowing users to check their BAC before driving.
  • Enhances safety at social events like office parties or corporate events by offering a convenient tool to monitor alcohol intake.
  • Offers peace of mind to individuals who want to ensure they are fit to perform tasks requiring full attention.
  • Supports health and well-being by encouraging moderation in alcohol consumption.
  • Acts as a preventive measure against potential penalties related to drink driving. These include finesalcohol interlock program, or jail time.

How a Disposable Breathalyzer Works

A disposable breathalyzer works using a chemical reaction. When a person exhales into the device, their breath comes into contact with a chemical compound inside the breathalyzer, such as potassium dichromate. As the breath passes through a tube, it reacts with the chemical, causing it to change colour or undergo some other detectable change.

This chemical reaction occurs due to the presence of alcohol molecules in the breath, specifically ethanol. Ethanol is a volatile compound found in alcoholic beverages. When an individual consumes alcohol, the bloodstream absorbs ethanol. Eventually, the lungs release it when the person exhales.

Once the breath containing ethanol reaches the chemical compound inside the breath testing device, it oxidizes the potassium dichromate. This oxidation reaction causes the colour of the chemical compound to change. It indicates the presence and approximate concentration of alcohol in the breath. By comparing this colour change to a reference chart on the breathalyzer device, one can estimate their breath alcohol content.

Factors that May Affect the BAC Levels the Device Can Detect

Understanding the factors that can impact breath test results is crucial. Firstly, the elapsed time since the last consumption of alcohol can influence the outcomes of a disposable tester. Consequently, if a person has consumed alcohol recently, the tester might indicate a higher BAC level. Secondly, the presence of mouth alcohol. This occurs when someone uses mouthwash or breath spray shortly before the test.

Lastly, environmental conditions, including low or high temperatures, humidity, or air quality, can affect the accuracy of the test results. Therefore, it is crucial to assess the surroundings and the state of the testing unit before proceeding with the test.

How to Use a Disposable Breathalyzer

A disposable breathalyzer is a practical tool that helps make communities safer by preventing individuals from driving under the influence. To use this prevention tool, the person should first remove it from its packaging and make sure it is fully intact. Then, they have to carefully hold the breathalyzer by the mouthpiece and ensure that it is facing the right way.

Next, the user should take a deep breath and place their mouth over the mouthpiece, making sure to create a tight seal. They should exhale smoothly and continuously into the device until their lungs are empty. It is important to ensure that no air escapes from the nose or sides of the mouth during the process.

After providing the breath sample, the person should wait for a few moments for the device to analyse the breath. Following this short waiting period, the breathalyzer typically provides a visual indication of whether alcohol is present. After use, people can dispose of the device. Overall, this process provides a quick and efficient way for individuals to make sure they are within legal limits.

Accuracy of the Results

Many people choose to use disposable alcohol testers because they are convenient and affordable. However, compared to reusable breathalyzers, single-use breathalyzers tend to exhibit lower levels of accuracy. These portable and inexpensive devices are typically for personal use, providing an estimation of BAC levels rather than precise measurements.

Reusable breathalyzers, on the other hand, are more accurate and reliable than their disposable counterparts, especially those with fuel cell technology. These professional-grade devices are usually used by law enforcement personnel and employers and undergo stricter calibration and regulations. Nevertheless, disposable breath alcohol testers can still provide a reasonable estimation of BAC levels.

Conclusion

In summary, a disposable breathalyzer is a one-time-use device that gauges alcohol levels in the body of a person. It functions through a chemical reaction, where exhaled breath interacts with a compound, signalling the presence of alcohol. This immediate testing tool promotes responsible drinking and aids in assessing the readiness of a person for activities like driving. It is a practical and effective tool for fostering safety and preventing alcohol-related incidents.

Correct use of the device includes unpacking it, checking for any damage, exhaling deeply through it, and disposing of it properly. While these affordable tools offer a quick check for alcohol presence, their accuracy is lower compared to conventional breathalyzers. Though not as precise, they still provide a reasonable estimation of blood alcohol levels. People looking for professional-grade devices may opt for BACtrack S80 or SHIELD Express Identity from Breathalysers Australia.
