Tips on How to Buy a Breathalyser
It is a well-known fact that drunk driving is one of the hazards of public safety on the highway. To prevent accidents, breathalysers are used by law enforcement officials as a non-invasive way to estimate if an intoxicated driver is fit to drive or not.
A breathalyser determines the blood alcohol content (BAC) of an individual by collecting his/her breath sample. It uses a chemical reaction where it changes colour when it interacts with alcohol. The latest technological innovations are useful in producing breathalysers that have an accurate reading. They are now being used in personal and industrial applications.
Personal and Industrial Breathalysers
In purchasing a breathalyser, you need to know which application you are going to use it for.
Breathalysers are used in industries such as mining, factories, trucking, public transport, mining, aviation, and the military. It is also used in hospitals, clinics, treatment facilities, schools, bars, and in law enforcement.
More and more people are being made aware of the dangers brought by driving under the influence of alcohol. This is why personal breathalysers are becoming increasingly popular.
Affordable, Reliable, Convenient
With a personal breath alcohol tester on hand, you can check your level of alcohol consumption anytime anywhere. Here are some things to consider when buying a personal breathalyser:
Types of Breathalyzer Sensors
There are two types of sensors used in breathalysers for personal use – semiconductor and fuel cell technologies. The pros and cons will be discussed below.
Semiconductor Sensor – This oxide sensor is used to measure the reaction between the tin dioxide (sn02) bead in the sensor and the alcohol in the person’s breath. Blood Alcohol Content (BAC) is measured when the alcohol causes the change in the electrical resistance of the sensor.
Its advantages include:
Its disadvantages include:
Fuel Cell Sensor – offer extremely high accuracy and consistency on their results. The sensor applies an electrochemical process that oxidises alcohol and produces an electrical current to measure the alcohol content of the breath sample.
Its advantages are:
Its disadvantages are:
Regardless of the pros and cons, anyone can take advantage of these two technologies. A reliable breathalyser will provide accurate information as long as it is a product that passed Australian Standards and it can be calibrated to maximise its use and save you money.
