Breathalyser: Frequently asked questions

What types of Breathalyser are there and what determines a good product?

There are two types of Breathalyser, the Draeger Alcotest 7110 and the Intoxilyzer 5000. The Draeger is used in most states while some use the Intoxilyzer 5000. Both devices have their own advantages and disadvantages that you should be aware of before deciding which one to go with for your case.

The most important factor is the accuracy of the device. This means that it must be able to accurately measure your blood alcohol level, and not give false readings due to faulty equipment or human error. It should also have a good range for measuring different levels of intoxication, so you can get an accurate reading even if you’re only slightly intoxicated (or very drunk). Finally, it needs to be easy-to-use – there are many devices on the market which require too much fiddling around with before they will work properly.

Who should use a Breathalyser?

Anyone who is concerned about their alcohol intake.

Based on what criteria should you buy a Breathalyser?

Price, features and brand are some of the most important factors to consider when buying a Breathalyser. However, other factors that might be relevant include special features, warranty and availability. Make sure you compare apples with apples to avoid overpaying for a device or missing out on key functionality.

You should always look out for the quality of the product. It is important that you get a high-quality Breathalyser, which will be able to give accurate readings and last long as well. If possible, try comparing different products before making your final decision on what one to buy.

What are the advantages and disadvantages of a Breathalyser?


A Breathalyser is a device that measures the amount of alcohol in your breath. It can be used to test whether you are driving under the influence or not. This makes it an effective tool for law enforcement officers and other authorities who want to ensure road safety by preventing drunk drivers from getting behind the wheel. The advantage of using a Breathalyzer over traditional methods such as blood tests, urine analysis, etc., is its ease-of-use and convenience – no needles involved.


The main disadvantage of a breathalyser is that it can only be used to test for alcohol. It cannot detect other substances such as drugs, so if you are driving under the influence of these or any other substance then this will not show up on your device.
