A breath analyser is a device that measures the Blood Alcohol Concentration (BAC) levels of an individual using breath samples. It does this by measuring the amount of ethanol present in the breath. It is a convenient method of identifying alcohol misuse among individuals, particularly on roadsides or workplaces. There are several types, including ones with semiconductor sensors, fuel cell sensors, and those that use infrared spectrophotometer technology.

Besides professional devices, there are also personal units for people to buy. Breathalysers are useful tools that can help individuals monitor their alcohol intake. This can help them regulate their drinking and avoid the negative consequences of alcohol abuse. It is an ideal alternative to blood and urine tests that require special facilities to conduct. This article will present information on breathalysers, including the types, modes of testing, and where to buy them.

Breath Analyser Testing Modes

There are two types of testing modes available in breath analysers. Most devices will have an active mode. Using this, operators can receive a numerical estimate of alcohol in the blood. It requires the individual to directly blow into the mouthpiece of the device until they provide a sufficient sample. With this mode, testing takes a few minutes. Moreover, testing big groups will require the operator to replace the mouthpieces for hygiene.

The other mode is the passive mode. This is typically seen in professional-grade devices instead of personal breathalysers. A passive test only requires the person to speak or blow over the device, and it will receive an adequate sample. This is ideal for testing large groups because it is faster and does not require multiple mouthpiece changes. However, this mode does not provide a measurement of the BAC.

Ideally, organisations can first use the passive mode to swiftly screen individuals. If they receive a failed result, then they may proceed with an active test for a more accurate measurement.

How Does a Breathalyser Work?

• When a person drinks alcohol, ethanol gets absorbed into various parts of the body, including the mouth, esophagus, lungs, and intestines.
• As the blood containing ethanol passes through the lungs, ethanol may become stored in the alveoli as it evaporates.
• As such, when an individual blows into a breathalyser, it detects the ethanol from the deep lung air samples.
• The device uses a partition ratio, which is 2100 to 1. This means that 1 ml of blood corresponds to about 2100 ml of breath.
• The breathalyser uses this ratio to measure the BAC with its sensors.

Types of Breath Analysers

There are several types of breath analysers that people can use. Firstly, semiconductor breathalysers are one of the most common types. It is the least expensive and can be more compact than other devices. It uses a tin oxide compound to generate electric currents in proportion to the BAC level. However, it can be influenced by environmental factors, such as alcohol fumes, leading to false-positive results.

Secondly, fuel cell breathalysers are frequently utilised for professional-grade tests, such as for legal and workplace purposes. This type uses two platinum electrodes with an acidified electrolyte substance. The device oxidises the ethyl alcohol as it passes through the electrodes, turning it into acetic acid, protons, and electrons. The electrons produce a measurable current. These devices are also available for more accurate personal tests.

Lastly, a breathalyser using infrared spectrophotometer technology is usually only seen in police stations. Unlike semiconductor and fuel breathalysers, this is a desktop device that is not portable. It uses infrared technology to calculate the level of ethanol by measuring how much radiation reaches the other side of the collection chamber.

Applications of Breathalysers

People can use breath-testing machines in various settings. For personal use, it is an effective method for monitoring and limiting alcohol consumption. It can also help drivers avoid drink driving charges by ensuring they are sober before getting behind the wheel. Health professionals also use this device in rehabilitation centres to monitor recovery from Alcohol Use Disorders (AUD).

Law enforcement officers use breath testers for random roadside breath testing. This helps prevent roadside accidents, increasing road safety. Lastly, employers can conduct testing to ensure workers are not intoxicated on work sites or during business hours.

Where to Buy a Breath Analyser

Breath analysers are widely available on many platforms. They are popular devices that many purchase for personal and workplace use. Many physical stores offer a range of breath-testing products. This includes pharmacies, department stores, supermarkets, and specialty shops. It is a convenient option for people who need to use the device immediately.

Many also buy breathalysers online. Several online platforms have product listings for breath testers. Moreover, many manufacturers also have official websites that recommend authorised retailers or have devices available to buy. An advantage of buying online is that people can do this wherever and have the device delivered to their address.  Moreover, many also offer discounts and vouchers that can make it a more cost-effective option.

It is crucial to consider the type of sensor, price, calibration options, and warranty before buying a device. Interested buyers may view previous customer reviews for additional insight. Before buying the device, they should ensure it aligns with the needs of the user. One example of a reliable device is the BACtrack S80 Pro Gen1.

A Closer Look at the BACtrack S80 Pro Gen1

The BACtrack S80 is one of the most accurate and reliable personal breathalysers on the market. The S80 is tough, resilient, and clever and is always accurate and reliable. The S80 can be relied on as both a low-volume, entry-level workplace breathalyser and a high-end personal breath tester. 

The device has grade 9 fuel cell sensors, which provide high accuracy. Moreover, it utilises a one-touch operation that enables users to start testing in seconds. It has an audible alarm set to the Australian driving limits. Lastly, it is energy efficient and can power up to 1500 tests with a fresh set of AA batteries.

Conclusion

A breath analyser is a device that uses sensors to measure the BAC levels of an individual. There are several types that can fit professional, evidentiary, and personal use. Semiconductors are frequently used for personal devices because of their inexpensive costs and lower accuracy. Meanwhile, fuel cell breathalysers are more accurate, making them ideal for high-end personal testing, workplace screening, and roadside tests. There is also a device that uses infrared spectrophotometer technology, typically used in police stations for evidence purposes.

Generally, there are two types of testing modes. Active mode testing requires the person to blow directly into the mouthpiece of a breathalyser. This produces a numerical measurement of the BAC. Meanwhile, the passive mode only shows pass or fail results based on the limit. People can buy breathalysers online or in physical stores. Those looking for a highly accurate personal breathalyser may consider the S80 Pro Gen 1.
