Portable personal breathalysers — like professional models used by law enforcement officers during roadside checkpoints — can be an excellent preventive device for safe driving. Therefore, breathalysers are becoming more common and retail shops now offer them. BACtrack breathalysers at Costco are available for purchase. For example, the top-rated BACtrack S80 has an accuracy of +/-0.005% at 0.050%, which offers BACtrack’s highest police-grade sensor. When used correctly, breathalysers are accurate to a 0.001% margin of error.

These gadgets conduct alcohol breath testing, analysing and calculating your breath sample’s chemical composition to estimate your blood alcohol content levels (BAC). If you need a method for determining sobriety — blowing into a breathalyser is a practical way to confirm if you are fit to drive. This article will discuss how breathalysers work, their sensor accuracy and other features to consider when purchasing an alcohol breath tester.

BACtrack at Costco: How Do Breathalysers Work?

When you breathe into a breathalyser, the device sensors analyse the alcohol content in your breath sample. In most States, you can receive fines and possibly jail time if your blood alcohol content is 0.08 BAC or higher. Therefore, people who want to reduce getting into legal cases seek a convenient and accurate breathalyser like BACtrack at Costco. Knowing your BAC level can help you make more intelligent and safer decisions.

However, it is worth noting that alcohol breath testers are not foolproof, and results can be affected by human error and technical complications. This is partly why alcohol breath test results or BAC readings are considered objectionable trial evidence in some states. However, high blood alcohol content readings from a personal device should never be wholly looked at as a false positive by people. If there are any indications that you are impaired, you should not drive.

The BACtrack breathalysers at Costco are reliable and accurate devices that can provide blood alcohol content readings within 30 seconds. In addition, if your BAC level is below the legal limit and you are sure you are fit to drive is essential. On the other hand, if your BAC levels exceed the legal limit, you should wait until your BAC goes down and you feel safe enough to operate a vehicle.

BACtrack at Costco: Sensor Technology and Accuracy

All portable breathalysers work essentially the same way. You provide a breath sample and blow into a breathalyser. The device then measures the breath sample and provides a BAC reading. However, breathalyser sensor technologies and their accuracy may be different. It would help if you considered looking at BACtrack breathalysers at Costco and what sensors they have before purchasing a unit. Your choice will likely depend on your specific testing needs and situations.

The most important feature of a breathalyser is sensor accuracy. First, two standard breathalyser sensor technologies are semiconductors and fuel cell sensors. Traditionally, most alcohol breath testers use semiconductor sensors to measure BAC levels. Semiconductors are less expensive, however, less accurate than fuel cell sensors. In addition, semiconductors are more likely to produce false positives due to substances such as ketones. However, if it is only for at-home or personal use, these types of breathalysers may be adequately reliable.

On the other hand, alcohol breath testers that use fuel cell sensor technology are more sensitive than semiconductors and provide highly accurate BAC readings. In addition, fuel cell breathalysers are used by people who want reliable and police-grade accuracy. Moreover, fuel cell sensors only react to ethanol and are less likely to produce false positives. Consequently, they are an excellent choice if you seek the most accurate breath testing devices like BACtrack breathalysers at Costco.

BACtrack Sensor Technology

BACtrack has its proprietorship of semiconductor sensor technology called MicroCheck®. These sensors perform at a more reliable, higher level, and more accurately than standard semiconductors. In addition, all BACtrack pro-grade breathalysers use Xtend® Fuel Cell Sensors. BACtrack breathalysers with MicroCheck Sensors include:

• BACtrack S35
• BACtrack Go

BACtrack Breathalysers at Costco: Features

Various brands and companies supply breathalysers. However, if you seek the most reliable and accurate breathalyser, you should choose BACtrack Breathalysers at Costco. The breathalysers on the market have some significant differences, and some may offer features that others may not. When considering purchasing a personal breathalyser, you should consider the price. You may not need a high-standard unit that law enforcement officers use and want a less expensive model for personal use. 

Since accuracy is an essential feature of a breathalyser, you should get a fuel cell breathalyser. Blood alcohol content readings should be highly accurate and reliable to help keep you safe and reduce the risks of roadside accidents. In addition, some alcohol breath testers will display your BAC using LED display screens, while others have an optional Bluetooth smartphone connection like the BACtrack Mobile Pro. You should skip this feature if you do not want to use a smartphone.

Furthermore, all breathalysers require calibration after 6-12 months for the device to keep its accuracy. This is vital to keep your breathalyser unit reliable and provide highly accurate BAC readings. You should look for BACtrack breathalysers at Costco if you require personal breathalysers. Access to quick and easy breath testing is beneficial as you can check and monitor your BAC levels.

Factors that Can Affect Sensor Accuracy

If you know the features of a breathalyser that you need, you should also know some factors that can affect the accuracy. Here are a few factors to keep in mind that can potentially cause BAC reading errors: 

• Foreign Substances
• Calibration
• Software
• Operator Error
• Consistency
• Environmental Factors

Conclusion

In conclusion, the accuracy of BACtrack breathalysers at Costco will depend on the sensor technology. However, many factors may determine alcohol breath tester accuracy. You should get a fuel cell sensor breathalyser if you require high-standard and highly accurate BAC readings. On the other hand, if you are on a budget and still want to ensure safety, you may get the less expensive semiconductor models. Whichever you choose, BACtrack ensures you get an accurate and reliable BAC reading.
