Any digital breathalyzer has the potential for experiencing problems in accuracy due to changes in ambient temperature, surrounding air temperature, and temperature of the person giving a breath sample. Many of the newer devices feature what is known as "fuel-cell technology" for detecting alcohol particles in the breath. In a fuel cell digital breathalyzer, internal platinum plates produce a chemical reaction as the alcohol particles oxidize. This process results in an electrical current which aides in giving an extremely accurate reading. Most mini digital breathalyzers require no mouthpiece, and many of the mini breathalyzers are very high in quality in comparison to some of the larger clinical type devices. Using a digital breathalyzer, it is a fairly simple process to quickly collect a blood alcohol content (BAC) estimation. You will hear some interior movement which is the device clearing whatever air or other contaminants may be present within the device. A typical digital breathalyzer will display a zero when it is ready to collect a breath sample.
Not anymore...Introducing the AlcoMate Breathalyzer AL7000. The AlcoMate Breathalyzer has now solved the problem.
You forgot to read the fine print.
All breathalyzers have a sensor module (the part that determines your blood-alcohol-content) that degrades over time. Pay the shipping cost. Now there is a state-of-the-art alcohol detection device that completely eliminates the re-calibration process. AlcoMate's Breathalyzer uses a sensor module that you can install yourself in under a minute. Pop out the old sensor. The AlcoMate Breathalyzer AL7000 also has a 4-digit back-lighted readout, making it easy to read day or night. AlcoMate's AL7000 combines the latest PRISM (Pre-calibrated Replaceable Intelligent Sensor Module) technology, professional accuracy and sleek, modern design into a convenient, easy-to-use unit.
