What factors are important in choosing a breathalyzer?
Accuracy is likely the most important factor when making a breathalyzer purchase, so you should consider the Sensor Type – Semiconductor versus Fuel Cell. Essentially, both options will provide accurate readings and the degree of accuracy will increase with the price.
Breath Sample Collection is an essential factor, and critical to an accurate breathalyzer reading. While the use of mouthpieces is one element that aids in obtaining breath samples that exclude external air, other aids to accuracy are found in the actual product design. For instance, the miniature air pump featured in the AT8030, AT8020, AT8080,AT8801 allows for the highest level of precision in collecting a breath sample. During use, the user can actually feel the "click" of the pump collecting the breath sample.
Lastly, you should look at the Brand of Breathalyzer you are purchasing. The manufacturer should be reputable, in the business of selling breathalyzers, specifically, for an extended period of time and have the endorsement of professionals and press as a result of providing a quality and accurate product.
