Things you need to know about fuel cell breath alcohol tester

We now know that even small amounts of alcohol can impair someone's judgement and capabilities. Before getting behind the steering wheel, it’s important to be absolutely sure that you’re fit to drive. That means being safely below the government alcohol limit. To test for the presence of alcohol on someone's breath you need a breath alcohol tester that is portable, easy to use, accurate and consistent.

At the heart of the breath alcohol tester is the sensor array, there are two primary categories of breathalyzers based on the sensor technology used: fuel cell sensors and semiconductor sensors.

The fuel cell sensor uses chemical reaction between alcohol molecular and platinum electrode's oxidization. The reason why fuel cell sensor has high accuracy is that platinum electrodes oxidized only with alcohol molecular and the oxidization volume is proportional with alcohol concentration which help to get very accurate test result. The more alcohol is present the greater voltage the fuel cell generates, leading to a higher reading.

Some of the advantages of fuel cell sensors:
Sensor is highly specific and sensitive to alcohol.
High accuracy. Being able to provide BAC readings to 3 decimal places at a smaller accuracy range of +/-0.005%BAC.
More stable and reliable. Most fuel cell breathalyzers require recalibration only once per year.
Long working life. Fuel cell breath alcohol tester has an expected working life of 3-5 years.
