Breathalyzer Buying Guide

The market for breathalyzers has become much more saturated with a range available. Increasing your knowledge before you buy will ensure you buy the best breathalyzer for the money and what works for you.

There are many factors to consider and what you will use it for. For example many people will want to own one so that it acts as a deterrent before you get in the car in the morning after a boozy night.

Types of Breathalyzers

In short, there are three different types of devices you can buy that include fuel cell sensor, semiconductor sensor and disposable units. The differences are usually found within the prices, designs and of course the accuracy.

The fuel cell sensor is the most accurate form of sensor found within the best breathalyzers. It measures the concentration of alcohol molecules per use and is only found with premium models. They will need re-calibration within a years of use but this is a small price to pay for top accuracy.

Semiconductor sensors are much smaller in size and have a medium degree of accuracy and are much cheaper. However, if budget is the most important factor, the disposable unit is the best buy but accuracy will not be what you would think.

Mouthpiece Hygiene

Nobody likes to spread germs even if is your friends or family. Between tests, you should switch between mouthpieces for better accuracy and hygiene. It is very easy to cross contaminate when someone has used the device before you have.

Mouthpieces are fairly cheap and it is better to buy in bulk than use old dirty ones at a later point.

Should You Rely on a Breathalyzer

All of the recommended breathalyzers mention within this article are very accurate and dependable. However, they will not provide the accuracy of what the police will use because these usually cost 5 figures.

Use these personal breathalyzers purely as a deterrent to stop you drink driving.

Budget

Buy cheap, buy twice is a phrase that states what will happen if you go for an ultra cheap breathalyzer. The less you pay, the less accurate the device will be and not to mention the quality of the sensor that it will be using.
