Best Mini Breathalyzers Buying Guide & Reviews of 2019

Breathalyzer, short for breath analyzer, is used for estimating blood alcohol content (BAC) from a breath sample. With this simple test, you can determine whether you are within the legal limits of alcohol consumption or not. Breathalyzers are considered the most reliable method to find out BAC levels in the blood. Easy-to-use and super handy, this machine requires the driver to just give a breath sample for an instant result.

Responsible drivers always take matters in their own hands by finding out whether they are within the legal limit before they get to the driver’s seat. You can do this too by getting yourself a pocket Breathalyzer.

Types of Breathalyzers

Before considering any breathalyzer for buying, it is imperative to learn about two different types of breathalyzers.

Semiconductor

In such devices, an internal reaction is created when the test subject exhales ethyl alcohol into acetic acid and water. This triggers an electric current the amount of which is assumed to be proportional to the amount of alcohol in a person’s blood.

The device using semiconductor sensors are perfect for personal or home use as they are not considered very accurate. Also, they are pocket-drilling and sometimes give false positives. The sensors in this machine are sensitive to products like hairspray and cigarette smoke.

Passive Breathalyzers

The passive breathalyzers come with internal fuel sensors that do not require you to blow into the device. The device is capable of detecting alcohol presence when you exhale, just like at normal times. The passive breathalyzers are used by law-enforcement officials to take a preliminary test to detect whether the person has consumed alcohol or not.

Active Breathalyzers

The active breathalyzers require you to blow air into the mouthpiece for it to detect the presence of alcohol content in your blood. These are used by law enforcement personnel to take preliminary tests and evidential breath tests. The results of active breathalyzers are almost always accurate and their results are presented as evidence in the courtroom.

Things To Consider Before Purchasing A Breathalyzer

In order to effectively determine BAC levels, it is important that your personal breathalyzer meets the legal standards. It is not recommended to buy a device that is not certified as it will provide false results and put you at risk on the road.

Calibration

Most of the breathalyzers come with sensors that provide the BAC measurement. Over the period, sensors tend to become less accurate. Therefore, look for a device that can be recalibrated to restore its previous accuracy levels.

Accuracy Levels

BAC levels are converted into numbers. A device with accuracy levels up to +-0.01 is ideal to use.

Instruction Guide

There are different types of devices in the market using different techniques. Every model comes with a user guide containing clear instructions that enable you to get familiar with the usage of the device. A pocket guide should be there to analyze the results properly.

Fuel Cell

These sensors use two platinum electrodes with electrolyte material. It oxidizes alcohol in a breath sample and produces an electric current to determine alcohol levels in the blood. These are professional grade breathalyzers and used by law enforcement officers. They are deemed highly accurate and expensive.

Pro-Tip

Remember to use it at least 20 minutes after your last drink.

Pricing

The price of breathalyzers varies vastly. The price for semiconductor breathalyzer starts from $80 and the price of fuel cell breathalyzers starts from $180. These prices can go up to several hundred dollars depending on the brand and the quality.

Warranty or Replacement

These devices are highly sensitive. For instance, after a few uses, it may not be accurate or dropping it on the floor might damage it. In such situations, you must be able to replace or recalibrate the device. Therefore, look for a brand that offers either a warranty or a free replacement.

Conclusion

Breathalyzers are the best way to enjoy a party and stay safe. Meanwhile, it is important to know that legal BAC levels vary from state to state. Be aware of the government’s legal limits before you go behind the wheels after drinking. A DUI is and highly preventable. A breathalyzer test before leaving the party will certainly save you from unnecessary troubles. Try our tailored list of top ten Breathalyzers to have a hassle-free purchase.
